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 sessions involving experts are currently held over conferencing tools such as Google Meet. Once the session is confirmed, we send out a Google calendar invite to both the candidate & expert with a conference link.

We are planning a migration to Zoom very shortly, so you might get a Zoom link instead.


To protect the privacy of both sides, we recommend audio, and perhaps screen-shares when necessary.

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.

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 clear 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. 70 USD), and we'll coordinate with the expert to refund the difference (eg. 30 USD). 

Please do note, your expert spent a lot of time in that session, so we ask you to be thoughtful of their time and effort invested too. However, it is your decision and 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 as many specifics regarding how the session didn't work as possible - we take refund requests very seriously, and need all possible information in order to have a deep discussion with your expert, so that where there was a genuine problem, they can learn from the experience and improve their services.

Please do note - all information provided in the feedback form, and across any other channels that you share with us regarding this session, may be shared with the expert. This is because they will reasonably expect to be told why their payment for the session is affected.

Both 1 and 2 must happen within 24 hours of your session being completed.

Important: 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 - when this accusation is made, we 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 they were, then a refund is not possible. However, 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, in a single mock interview. For some roles, candidates request 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.

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

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 usually about 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 50$ for sessions within the next 24h, and an extra fee of 25$ for requests within the next 48h.

- Experts from a specific location (usually free for Product and Engineering roles, but charged for roles with fewer experts - up to 100$ extra depending on geography)

- Experts with a specific experience level (25$ extra, and we can't always  guarantee this since we might not have an expert whom fulfils your request)

- 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 15$. Targeting a specific expert profile can cost between 20$ 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?

The discount depends on how many sessions you book, and the role for which you are interviewing.

For mocks with a first-session price of 99$, the discount is as follows:

5-7 sessions booked together: 50$ discount applied (~10% off)

8-10 sessions booked together: 100$ discount applied (~13% off)

11+ sessions booked together: 150$ discount applied (~15% off)

Sessions booked can be used across 1 year. However, they must be invoiced together i.e. paid in one go.

The first session doesn't count towards the bulk booking since it is already steeply discounted.

Profile-specific charges are waived in all bulk bookings (i.e. same expert, new expert etc). However, we can't guarantee specific/new experts for all sessions since this depends on expert availability - we'll try our best to achieve your requests.

If a session is cancelled/refunded for any reason - the discount will be removed or reduced first depending on total #sessions completed.

If you'd like to book additional sessions after completing the discounted ones, the price will default to the original.

If you'd like to book multiple sessions, and are interested in the discount level - please email us on support@prepfully.com. However, we'd always recommend doing 1 session first and assessing for yourself how useful the service is, before making a bulk booking.

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?

If your expert hasn't joined the session, please follow these steps

Stand by for 5-10min. Sometimes (especially on weekdays) they might simply be running late from a previous meeting. Do rest assured that they will provide a full 60-minute session to you.

Notify us. 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.

Drop off after waiting for 15-20min. We deeply apologize for this situation and will figure out a new slot for you immediately, ideally with a new expert. If you prefer a refund, we can also issue this right away. 

This happens super rarely (usually an expert facing some sort of emergency); but we know that doesn't make it any easier to bear.

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?

No. Some sessions were previously recorded when transcripts were requested (with coaches' approval, of course). This service is not offered on Prepfully at the moment.
