From FAANG to early-stage startups — Clevly has helped thousands land their offer.
“I used Clevly for my Google loop and got the offer. Real-time answers during system design were a game changer. Worth every penny.”
“As a PM, behavioral questions are everything. Having AI structure my STAR responses in real time gave me so much confidence. I stopped rambling and started landing offers.”
“The screen capture feature is insane. It reads the LeetCode problem and gives you hints without giving away the answer. Helped me think out loud properly.”
“I was skeptical at first but the WDA invisibility actually works — tested it with TechSmith and OBS. The app is completely gone from recordings. Game changer.”
“The mic transcription is nearly instant. By the time I finish hearing the question, the AI answer is already showing. It's like having a brilliant friend whispering in your ear.”
“3 offers in 2 weeks. Clevly kept me calm and the structured answers made me sound way more senior than I am. It's like having a coach in your ear.”
