Testimonials

Hear from attendees

"PrepFlow felt harder than the real interview. But the feedback was spot-on, and I walked into my next interview with much more confidence."

James Whiteley

Senior DevOps Engineer

"The scenario-based questions were very similar. The tips on design and incident responses taught me a lot."

Priya Nair

SRE Lead

"I’m so used to being ghosted after interviews — this was the first time I got clear, detailed feedback on how I performed. It felt good to finally know what I was doing well and what to work on."

Nathan Hammonds

Infrastructure Engineer

"I tried the CV review (for free), my CV now clearly shows impact, and already a few recruiter callbacks."

Laura Chen

Data Scientist

"Coming from a bootcamp, I was nervous. The interviewer was patient, explained my mistakes, and even gave me tips on how to structure my answers better. The follow-up feedback report was really constructive."

Ahmed R.

Junior DevOps Engineer (Grad)

"The live session pushed me out of my comfort zone in the best way. I finally understood where I was getting stuck in system design questions."

Elena Petrova

DevOps Engineer

"The mock interview helped me realize I was overcomplicating answers. The structured feedback made it easier to improve fast."

Marcus Lee

Site Reliability Engineer

"I appreciated how real it felt. The mock covered edge cases I hadn’t considered, and the feedback helped me tighten up my thinking."

Sophie Martinez

Platform Engineer
