Why Prepfully is the Best Mock Interview Service

There’s no shortage of mock interview platforms out there, with options ranging from in-person coaching to entirely remote sessions. Some services are excellent, while most others fail to deliver, so it pays to do your homework before signing up. You need to carefully assess platforms beyond pricing and popularity. The key characteristics of the best services to look for include:

1. Role-specific coaching: Make sure that the service you choose provides mock interviews for your targeted roles, be it PM, PMM, TPM, PgM, EM, SWE, iOS, Android, DS, etc.
2. Company-specific coaching: Different companies have different interview formats and evaluation criteria. You need mock interviewers with real-time insight into your target company’ interview processes and can offer personalized guidance. Whether it is FAANG companies, DoorDash, LinkedIn, Uber, Capital One, Reddit, Palantir, etc., the platform should provide coaches from your target companies.
3. Custom interview prep: Many individuals require practice in specific parts of the interview process only. For instance, you can ace technical screens or coding interviews but feel shaky when it comes to system design interviews. Or you might feel less confident about navigating behavioral interviews and require personalized coaching to communicate your responses with nuance. Therefore, it is important to pick a mock interview platform that can provide specific sessions for different types of interviews, such as system design, analytical coding, behavioral, people management, etc.
4. Custom feedback: You need personalized feedback on your weak areas, delivery framework, speaking skills, etc., from interviewers who've been on the other side of the table. This can only be sought from experienced professionals.
5. Refund policy: Many mock interview platforms offer a full refund or partial refund policy if users don't find the session helpful or satisfactory. 

Other nice-to-have features include 

1. A lot of seasoned platforms now offer AI-driven mock interviews, which is essentially an AI interviewer that runs you through realistic questions and gives instant feedback. These sessions are typically lower-priced, for instance, they start at $25 on Prepfully for 5 sessions. AI-driven practice interviews usually include detailed feedback reports of the candidate’s performance along with a transcript of their entire interview.
2. If mock interviews provide additional guidance on resume writing and formatting, follow up strategies such as thank you emails, salary negotiation advice, and general career mentoring, it can help candidates across and beyond the interview process.
3. Recording and playback options, where users have the option to capture and transcribe can be helpful. This way, candidates can revisit their sessions later to analyze and identify areas that need improvement and work on them.

Here are the top features that set Prepfully apart from its competitors:

#1 Expert Coaches for Every Role & Company

Prepfully’s coach network is extensive — over 1,650 interview coaches covering almost every industry and role, including PMs, PMMs, TPMs, SWEs, DE, DS, EM, and more, from companies like Meta, Amazon, Microsoft, Netflix, Google, Capital One, etc. For example, as of August 2025, Prepfully’s coach count stands as follows:

• DS coaches — 184; which includes experts from Meta (47), Microsoft (37), Google (16), Amazon (36), 
• TPM coaches — 193; from companies like Meta (46), Google (49), and Amazon (64).

• EM coaches — 256; from Meta (56), Google (43), and Amazon (73).

The majority of mock interview platforms like Exponent, IGotAnOffer, Interview Buddy, etc., have far fewer numbers in every category as compared to Prepfully. Another important thing is that Prepfully coaches are handpicked after thorough vetting and their backgrounds, session numbers, and reviews are readily visible for candidates to review expertise depth and make an informed decision. For perspective, Prepfully has an average reviewer rating of 4.85 across roles.

#4 Anonymous Coaching

Another feature that sets Prepfully apart is that the mock sessions are totally anonymous. In our experience, most candidates appreciate this anonymity, especially those who’d rather their current colleagues not know they’re job hunting.

#5 Personalized Guidance

A Prepfully mock interview is a focused, 1-hour session with an expert—and by “expert,” we mean someone who’s actually been in your target role at your target company. They know exactly what gets you hired there. They’ll walk you through the interview process, flag the questions you’re most likely to face, and show you how to tackle them. 

Afterwards, you’ll get detailed verbal and written feedback (not generic “good job” comments, but clear, actionable pointers to sharpen your answers and boost your confidence). Plus one extra thing you won’t find in most mocks: the coach’s honest hiring decision, had this been the real deal.

#6 Refund and Cancellation Policy 

One thing Prepfully does differently — and better — than most platforms is its “refund of value” model. It’s fair to candidates and fair to coaches.

It is pretty reasonable and straightforward. If you didn’t find a session useful, you can request a partial or full refund within 24 hours (you’ll need to explain why and suggest what you think it was worth). Prepfully will loop in the coach and refund the difference if they agree. 

As for cancellations, you can cancel your booked mock interview session (with advance notice) for a full refund.

However, if the request for cancellation comes in within 24 hours of the scheduled session, you’ll be charged a 50% cancellation fee. No-shows usually aren’t refunded unless the coach was at fault. 

Bulk bookings follow their own refund rules, with amounts calculated per unused session.

Prepfully prioritizes coach fairness. accountability, and trust — exactly what you want from the best mock interview provider out there.

#7 High ROI

Hiring an interview coach almost always pays for itself many times over. For perspective, tech salaries in the US range from $100K all the way past $2M annually. A mock interview session on Prepfully costs you $50–$300 (average ~$150). These fees represent a tiny fraction of the annual salaries secured through successful interviews. 

Candidates aiming for Google, Meta, Amazon, or similar companies routinely report securing offers with an average salary increase of $30,000–$50,000 (and sometimes much higher in competitive tech roles). Therefore, booking a couple of Prepfully sessions is essentially a no-brainer considering the high ROI.

#8 Additional Services

Prepfully specializes in resume reviews. An expert panel made up of seasoned recruiters and hiring managers deep dives into your resume and provides detailed, actionable feedback on how to make your resume stand out in a crowded pile. Written reviews have an average

Prepfully is currently also experimenting with different transcription providers to provide transcripts for all interview sessions. Transcripts are typically available about 30 minutes after the session ends, however this does not apply to all coaches (make sure to check when booking if session transcripts are a deal breaker for you).

Anyway, we've said our bit, now we'll leave it up to you to decide.

If you need to schedule a mock interview for an upcoming interview, you can always rely on Prepfully. You can book with interviewers who’ve worked at Meta, Amazon, Microsoft, Netflix, Google, and Capital One, matched to the exact role you’re targeting.
