Lots of stuff on Prepfully is free. Our interview Question Bank is completely free, as are the Interview Guides. For some of our products (which involve experts), there are fees associated. We’ve very competitive in our pricing though - and we offer no-questions-asked refunds if you ever feel you didn’t get the value you’re looking for.

Prepfully is an interview prep startup. We're a bunch of people running it as our weekend project. Our experts are people employed at top companies all over the world, and help candidates as a side-gig when they have time.

Prepfully is the go-to place for your interview preparation through mock interviews.

Privacy is super important to us - we go the extra mile to protect it so you feel safe.

All your data is protected. Our website is completely secure. 

If you use a product involving experts, we give you the option to share your resume so they can customize their advice to your background/ context. Experts know that they need to keep this confidential. However, this is optional; if you don't want to share it, the system still works.

Finally - we recommend practice interviews be done over audio. That adds one additional level of privacy too.

We go the extra mile to protect your privacy. All your data is protected. Our website is completely secure. 

All Prepfully sessions are currently conducted over Zoom.

Once the session is scheduled and confirmed, you'll receive a calendar invite with a conference link. The link will be shared with both the candidate and the expert.

We recommend audio calling (and screen sharing where necessary, of course) to protect the privacy of the candidate as well as the expert, and use of video only if absolutely necessary and mutually agreed.

PS - we're constantly trying new tools which help improve the experience and protect all participants' privacy, so you might sometimes get an invitation to use something completely different too. 

If you have ideas re: alternative tools which work better - please definitely send them across to us on support@prepfully.com.

All sessions involving experts are currently held over conferencing tools such as Google Meet.

How do I connect with Prepfully’s experts?

We do this at our end. Just as we are committed to protect your privacy, we also protect our experts’ - and therefore we only share an anonymized profile and relevant experience with you once your session is booked.

We only share an anonymized profile and relevant experience with you once your session is booked.

It shouldn’t – we ask experts to declare a conflict of interest in their company if they are ever asked to be part of your actual hiring process.

Can a session with an expert working at my target company affect my hiring process?

Yes, we do share an anonymized profile of your expert, along with the sections of their experience which are relevant for your request. However, personal details are not revealed in order to protect their privacy. Check out our privacy policy for the full set of details.

we do share an anonymized profile of your expert, along with the sections of their experience which are relevant for your request.

Will I know the profile of the expert who’ll take my session?

We’ve got a robust matching algorithm to ensure we find the best possible expert for your requirements.

However, you have the option to reject the expert within 24h of a session being scheduled - we’ll find a new expert for you. Please do note, that if your request is profile-specific, there might be extra charges associated with it (more details here)

In addition, we can't inquire into our expert's specific teams in the company they're working in, since this constitutes confidential information. We do of course support matching title ranges.

You always have the option to cancel the session, and as with all cancellations requested by a candidate - we'll issue a full refund minus PayPal's transfer fees, if there are any.

What if I do not find the expert profile suitable to take the session?

First off, we apologize for your negative experience.


Please give us details here, or email us at support@prepfully.com right after the interview. If you provide specifics of what went wrong within 24 hours of the session, and it's clear that your expert failed in delivering upon any realistic expectations you might have requested for your mock interview experience, we will offer you a refund of value. 

A refund of value is where you tell us whatever you think the session was worth; we'll reach out to your expert to notify them, and then refund the difference. For instance, if you paid 100 USD for a session but there was a  failure on the part of the expert to deliver a relevant interview experience, you can then tell us how much the interview was worth to you (eg. 50 USD), and we'll coordinate with the expert to refund the difference (eg. 50 USD). 

PS - your expert spent time preparing for and coaching you in a session -- so we ask you to be thoughtful of their time and effort invested too. However, it is your decision and the refund amount is your call - we trust you to make the right one. 

You will need to have filled out your written feedback form answering all relevant questions that you would have received immediately after the session.

You'll need to send us specifics regarding how the session didn't work as possible - we take refund requests very seriously, since our entire premise is to have great coaches who can deliver great experiences for candidates (i.e. the sort which don't trigger refund requests) - and detail ensures your coaches can either learn from the experience and improve their services, or be removed as coaches from the platform.

For special circumstances (for instance, if you felt your coach made you feel unsafe), please make sure to let us know when reporting a refund request. We have a special process for this; and will make sure your coach will not see your feedback. 

Important: Please note, these steps must happen within 24 hours of your session being completed. Once 24 hours have passed, we can unfortunately not support refund requests. This is because 

Experts have already been paid by this point, and it is not possible to claim payments back. 

Experts' and candidates' memories remain fresh only up to a certain point. Longer periods lead to disagreements and misrepresentations of what really happened in-session.

The 24 hour rule protects our experts from fraud, as well as protects Prepfully from perpetual liability.

Is "my actual interview was nothing like the mock interview" a legitimate reason for requesting a refund?

To explain further - this first depends on whether you picked a coach or were matched with a coach who has worked in your target company and role.

If you either picked a coach or accepted a coach who isn't an exact fit for the role you are interviewing for - they are not expected to know the interviewing process of your target company. They will simulate an interview for the role you have selected, and respect any special request you have provided. For instance, if you are interviewing at Dropbox for a Product Manager role and choose a Meta PM to practice Behavioural, the Meta PM will simulate a PM Behavioral interview but will not simulate a Dropbox-specific Behavioral interview. Therefore, "my Dropbox interview was not like the mock interview" is not a valid reason for a refund. However, "my mock interview didn't cover behavioral questions" is a valid reason for requesting a refund.

However, if you were indeed matched with a coach from your target company and role, and you report the interview simulation didn't match reality - we quickly investigate your target company/role's interview process to verify if the topics covered by the expert were (a) relevant and (b) in line with any request you might have provided through Prepfully. If either of the two conditions above were not satisfied, you will be entitled to a refund. In this case too, a request must be made within 24 hours of the session being completed.

Please do note, it would be impossible for one expert to cover all possible topics, themes, or questions, that an actual interviewer might cover in the live interview loop, in a single mock interview. For some roles, candidates book several mock interviews to cover an array of topics. This can help you ensure greater coverage over topics which will happen in your actual interview. If you have a special request (eg. "portfolio review type interview" for a Product Designer role, or a "Product Sense" style interview for a Product Manager role), then you always have the option to send this through us in advance, and your expert would be happy to customize the interview based on this requirements.

Why doesn't Prepfully bear the cost of a refund itself?

We actually do -- when we make a mistake we bear the cost of a full refund, and fix it ASAP - we are bootstrapped and would go out of business pretty fast if we didn't. In situations where we don't feel we could have done more to pre-empt a refund, it is borne by both Prepfully and the coach.

Some examples of situations where we've issued refunds in the past (a total of 16 such refunds so far, out of thousands of completed sessions -- fingers crossed it doesn't go up)

[2023] A candidate requested a "TikTok PM" interview. We matched them with a PM from Bytedance. We mistakenly mapped TikTok and Bytedance as one company. We now have 6 TikTok PMs and 2 from Bytedance. Candidate offered free session in lieu.

[2022] A candidate requested a QA Engineer who could provide them practice in "Cypress and Typescript". We missed sharing this when reaching out to coaches, and the coach matched proved to be an expert in "Java and Selenium Webdriver but not at all in Cypress and Typescript" (reported by the candidate). Full refund offered.

[2021] A candidate requested a "Meta Product Design" interview. We matched them with a Product Designer from Meta. It turns out "Product Design" is an interview type for Software Engineers and EMs. We now have 23 Meta engineers supporting Product Design interviews for engineers. Candidate offered free session in lieu.

[2021] A candidate requested a "Product Design Engineer" interview. We matched them with an Apple UX Designer. We didn't realize at the time that Product Design Engineering was a hardware engineering role. We now have 16 PDEs + Mechanical Engineers from Apple, Meta and Google. Full refund offered.

[2021] A candidate requested a Meta PM mock interview, and they got matched with a Meta Product Growth Manager. We now have 44 Meta PMs, so we won't make that mistake again! Full refund offered.

However, in situations where either a coach doesn't provide a mock which respects requirements, or is rude/unprofessional, or is unable to provide a proper mock interview simulation or coaching experience -- the cost of a refund is borne by the coach.

Are there any scenarios where Prepfully doesn't support refunds?

If you miss a session, and a coach marks you a no-show (coaches will always wait 20 min before they can mark you a no-show, and are required to upload screenshots and timestamps proving that you weren't in a session), we will not be able to issue a refund or a free reschedule.

If you request a specific coach and find out after the session that you booked the wrong coach by accident - we won't be able to issue a refund. Please read the coach profile carefully before booking; and cancel in advance to get the relevant refund amount. You're always welcome to request a refund if you don't like the coach you're scheduled with - Prepfully transparently links in the coach profile once your session gets scheduled. This is particularly important to do if you've chosen "coach agnostic sessions" i.e. either if you've provided a company-role combination and allows Prepfully to schedule a coach for you; or absent a relevant matching coach, if you've selected alternative companies' coaches with whom you're OK completing a mock. Naturally, if a coach has misrepresented their employment, this exclusion doesn't apply. We verify coaches' employments though, so if you feel a coach has actually misrepresented their experience - we will request proof.

If you've provided an unrealistic scope (eg. covering 4-5 different formats in one hour) - this session becomes nonrefundable. Coaches are humans too; and can only cover so much ground within a single session. It will never be viable to properly simulate two or three one-hour interviews within a single one-hour session, so if you're requesting a larger scope than an interview requires - we pre-manage expectations that this will come at the cost of breadth and depth within one specific topic.

Please give us details here, or email us at support@prepfully.com.

What if I did not find the session with the expert useful?

Prepfully has a balanced reschedule policy

It's free to modify slots (or cancel a booking) before it gets scheduled. It costs $25 to modify a session after scheduled; modifications less than 24h prior to a session cost 50% of the session price. And sessions cannot be modified or refunded after the start of the session time; coaches will wait 15min before marking a session a no-show.

Prepfully balances your (the candidate's) need for flexibility, with your coaches' need for certainty that the time they're blocking will manifest in a payout. Many Prepfully coaches support mocks across a range of platforms, and we expect them to decline these paid commitments once a Prepfully session is locked in. 

Having said, that for both candidates and coaches -- sometimes, "life happens", and a reschedule is needed. Therefore, we help out when we can. 

In much the same way as when you book a flight - if you need to change the date, you will need to pay for this change. If you miss the flight (i.e. your session), your coach will still need to be paid for it, so you cannot get a refund if you miss it. But if your flight gets cancelled (i.e. if your coach cancels your session), you get a free reschedule, or a no-questions-asked full refund.

We only charge where we need to, when there are either costs to cover coach fees, or support / staffing costs to assist with reschedules. We try to make charges are reasonable as possible, unlike most of our competition who absolutely refuse to assist with reschedules less than 24 hours away.

Prepfully supports most reschedule and cancellation requests for free. From the moment you book a session, until the session time is locked in, your reschedule is free. Likewise, if your session is far out and you cancel with a good amount of notice, and don't have a history of abusing this modification functionality - Prepfully usually waives the modification costs too.

However, if your session is just around the corner, your coach will naturally expect to be paid for the time they blocked. Therefore, for modifications less than 24 hours away - there is a 50% modification fee. And if you miss your session, coaches need to wait a full 15 minutes before they can mark you a no-show. After this - regretfully we will not be able to help, unless you've explicitly agree to a free reschedule with your coach in-session.

Here is a simple overview of Prepfully's modification costs:

From booking time - until the session time is locked in, pausing a session, modifying your availability, or cancellation is FREE. This accounts for the vast majority of changes, so for 90% of all modification requests, Prepfully manages to achieve these for free.

Once session time is locked in - until 24h prior to the session time - Reschedules, cancellations or changes cost 25$/modification

From 24h before the session time - session time - Reschedules, cancellations or changes cost 50% of the session price.

After the session has started (no-shows) - reschedules or cancellations isn't possible, unless your coach didn't show up, in which case you are entitled to a full refund or a free reschedule. A Prepfully coach can only mark you a no-show after a minimum waiting period of 15 minutes.


If one or more sessions from the bulk booking are cancelled by you – the refund is calculated as follows:

Each session reverts to its non-discounted rate

Refund amount = “total paid for the bulk booking” minus “all completed sessions at the non-discounted rate”

As an example, if you purchase a 5-session bulk booking for a $200 coach at a 10% discount (i.e. $1000 $900), but then cancel 2 bookings: you will receive $900 minus 3 x $200 (undiscounted rate) = $300.
As another example, if you purchase a 3-session bulk booking for a $200 coach at a 50% discount (i.e. $600 $300), but then cancel 1 booking: you will receive $300 minus 2 x $200 (undiscounted rate) = -$100. You will effectively not receive any refund in such a situation.


Please reach out to support@prepfully.com for any questions or concerns, or if you encounter a bug.

The first reschedule is always free, and can be done up to 24 hours before the originally scheduled time. Cancellations are free until a session is picked up by an expert - after which there are fees associated.

What’s the reschedule and cancellation policy?

We collect payment at the time of scheduling, so that we can guarantee it for our experts. Therefore, the due date is always prior to a session, and if payment is not received by then, the session will be cancelled.

How can I give any feedback to Prepfully?

You can provide special requirements to your expert in the special requests field. 

For specific roles, you can also specify the interview type you're looking for (eg. for Engineering roles - coding, system design etc). Do note, some interview types are priced differently; eg. System design mocks are sometimes 25$ higher than coding mocks since they rely on more senior experts who have sufficient expertise to take these sorts of interviews.

If you have a request to Prepfully, please send this to us via email. Some special requests we try to support include:

- Urgent requests i.e. less than 48 hours away. There is an extra fee of 49$ for sessions within the next 24h, and an extra fee of 29$ for requests within the next 48h.

- Experts from a specific location (often free for Product and Engineering roles in Google, Meta, Amazon etc, where nearly all our coaches have worked in the US but charged for companies or roles with fewer experts - up to 100$ extra depending on geography)

- Experts with a specific "years of experience" level (25$-200$ extra, and we can't always  guarantee this since we might not have an expert whom fulfils your request - we'll let you know upfront if we can't)

- Experts with a specific seniority title (For instance, if you select "UX designer", we will avoid matching you with "Sr. UX Designers" since they are priced differently. And the opposite works too; if you request a Sr Product Manager you won't be matched with a Junior or Core level Product Manager.)

- A specific expert profile (eg. one you might have seen on our YouTube channel, or a previous expert you might have encountered which you want to target or exclude). Exclusions cost 10$. Targeting a specific expert profile can cost between 25$ and 200$ extra depending on the expert.

Please note, if we're unable to fulfil your requirements, we'll always provide a list of alternative profile options to choose from over email. And if none of them work for you - we either won't collect payment, or issue a full refund if you've already paid.

How do I provide additional requirements?

You can "pause" a session if you think you'll use it at a future date. You can use a paused session any time across 3 years.

We just pause outreach to experts. You can resume the session directly from your session link anytime you want. Just make sure to update your latest availability.

This is only possible if your session hasn't been scheduled yet. 

How does pausing sessions work on Prepfully?

Yes, you can make bulk bookings on Prepfully. In fact - a lot of Prepfully coaches have configured discounts for bulk bookings. You'll be able to see this directly within the options to book the coach. 

You can also provide bespoke requests when making bulk bookings on Prepfully, such as "Please schedule by sessions with a 1 day gap between then". Naturally you'll also be able to provide specific session types and scopes for each session within a Prepfully bulk booking (eg. 5 sessions, of which 2 are system design, 1 is coding, 2 are behavioral).

Good to know: if a bulk booking is "partially cancelled" (Eg. by the candidate or the coach), the session prices falls back to the nearest discounted rate, or the non-discounted rate if you're already on the lowest. Therefore any refunds are issued after first reducing / removing discounts.

Yes, between 10-25% off depending on how many sessions you book, and the role you are interviewing for.

Is there a discount for multiple bookings

I'd like to book multiple sessions. Can I get a discount?

Once 15min have passed, you will be able to mark your coach as a no-show. Please use the "Mark expert as no-show" button in your session page. This button can only be clicked within the session window.

Your expert  gets notified to join when you start marking them as a no-show. If they join in late - rest assured that they'll provide a full 60-minute session to you.

If a coach doesn't show up even after 15-minutes, you can choose between a free reschedule and a full refund. 

Either way - we know that no-shows are super inconvenient and jarring; and therefore try very hard to minimize this. Coaches who don't show up twice in a row without an extremely good reason, are just removed from Prepfully, no matter how good they are. This keeps coach no-shows to less than 0.25% of all sessions.

Notify Prepfully. If the expert still hasn't shown up after 10 minutes - please take a screenshot, and reply to any of your confirmation or reminder emails to let us know. If we are online, we will help right away.

My expert hasn't joined the session, what should I do?

Yes, transcripts are available for the vast majority of sessions (98%). This feature is in Beta though.

Transcripts are typically available about 30 minutes after the session ends. Our system automatically processes the transcript using a service like Fireflies.ai, which takes up to 30 minutes.

To comply with privacy regulation, we need consent from coaches to provide transcripts. Some coaches prefer not to opt-in; in such session's transcripts won't be available. We're actively working to get more coaches on board.

Are transcripts available for Prepfully sessions?

tl;dr: The Dutch Tax Authority requires us to charge and remit 21% Dutch VAT to all bookers globally, not only in the EU.

Prepfully is currently registered in the Netherlands

We receive tentative guidance on 26 Apr 2024 that we might be required to charge Dutch VAT (21%) to all candidates globally.

After almost 10 months of discussions with more tax lawyers, accountants and authorities than we ever wanted to get to know - we received a confirmation from the Dutch Belastingdienst (Tax Authorities) on 11 Feb 2025 that we're required to charge and remit 21% tax on all transactions globally.

We are aware this is quite non-ideal, especially if you are not located in the EU

In transparency - we really dislike this additional tax burden too. Unfortunately our reasoning that VAT should be charged at the "location of consumption" was rejected by the Dutch authorities.

If you have connections to any (reasonably priced) international VAT consultants, please email us on tax@prepfully.com and we'll try to incorporate their input into our appeal.

Until then, we will (with regret, but without option) need to charge and remit 21% on top of every booked transaction. Due to the nature of taxation, we can't make any exceptions to this unless you are making a booking as a "business entity" rather than a "private individual".

The easiest way to cancel, is to go to your session link. You can access this either from your dashboard, or from the email you would have received when you booked it.

There's a cancel button in there - f you've already paid, the refund is issued immediately, with any fees being deducted if they are applicable. In most situations if it's your first cancellation and the session is a while away, we waive even the standard cancellation charge. This becomes harder to do if the session is less than 24h away, since 50% of a coach payment gets locked in at this point.

Important: The refund is issued instantaneously via Stripe (which we use as our payment provider). However, depending on your card provider, banks can take up to 5-10 days to show this refund in your statement.

If you don't see the refund for any reason, please just drop us a note on support@prepfully.com. We are all quite responsive, so you should hear back from us in less than a day (although we try to respond within a couple of minutes for topics like refunds unless we're asleep!)

For single session bookings
Yes, but only if the coach is unavailable. Since different coaches have different pricing, you might need to pay the difference if the replacement coach charges more — or get a refund if they charge less.

For bulk bookings
Switching coaches midway (e.g., after 2 out of 5 sessions) isn’t possible. If you want to switch, you’ll first need to cancel the initial booking; you’ll receive a refund for the unused sessions after removing your discounted booking rate. You can then choose to book an alternative coach (for however many sessions you think are useful), at the rates they’ve configured. 

Therefore, we always recommend first doing one session with a coach and assessing the value for yourself before making a bulk booking

Please note:⁠ ⁠not all coaches have configured discounted rates. Each coach decides this for themselves, so we’re not able to provide bulk session discounts in situations where a coach hasn’t configured these.

The allocation of your Prepfully coach depends on how you book the session.

You can basically choose to book a session in two ways.

Method one: Book a specific coach via prepfully.com/coaches

If you book via this channel: Prepfully's systems will exclusively approach that coach. 

If the coach is available in the slots you provide when booking, they will accept. 

If they aren't, they can choose to decline or counter with alternatives.

The system will not apply any level of intelligence for this mode, beyond following your explicit instructions. So it is quite important to ensure you choose the correct coach for your needs. 

You can expand coach matching to include other relevant coaches whom the system can approach in parallel. For instance, if you choose a specific coach who has past experience as a Sr DS at Meta, and they haven't responded for a while, we'll prompt you to check if you'd be OK with other coaches who have worked as Sr DSes at Meta. You're always welcome to keep waiting though; we introduced this option for candidates who care more about getting good quality practice than the specific coach they get it with (all active Prepfully coaches tend to be pretty good since Prepfully aggressively removes coaches who receive negative reviews).

Method two: Book a coach-agnostic session via prepfully.com/practice-interviews

When this mode is chosen, candidates provide a target company-role-seniority combination to Prepfully, and Prepfully allocates the a well reviewed "perfect match" coach who is available in your slots, to you. This is almost always the cheaper way to book a session. Prepfully defines a "perfect match" as a coach who EXACTLY matches the target company, the target role and has a greater than or equal to target seniority provided by a candidate at the time of booking. Thanks to a really large coach network, Prepfully is able to enable perfect matches for 87% of all requests.

If Prepfully doesn't happen to have any coach from your target company-role-seniority combination, the system will immediately flag this to the candidate, and you allow you to choose coaches who could be a potential fit. Good to know: 

Coaches chosen as alternatives when Prepfully doesn't have what we call a "perfect match" will not be These coaches will not be familiar with the nuances of the specific company you might be looking for. However, they will be masters of their craft and can simulate good craft-specific sessions for you.

However, in some situations, you might not want a coach who has only worked at alternative companies. You're always welcome to decline alternative coaches and mention "I'm not OK with any of these coaches". In this scenario, payment will not be collected from you; instead Prepfully will try to onboard a coach as quickly as possible, and notify you if we succeed in doing so before your slots expire. At that stage, if you're a "go" in terms of scheduling, Prepfully will request payment for the session.
