David
Software Engineer
Hired at Amazon
The real-time assistant was a game-changer during my technical interview. When I got stuck on a dynamic programming problem, it quietly suggested the right approach. I stayed calm, worked through it, and got the offer.
Sarah
Product Manager
Hired at Google
The real-time feedback pointed out that my answers lacked metrics. Once I started adding specific numbers and outcomes, my practice scores jumped and so did my confidence.
Emily
Data Analyst
Hired at Meta
SQL and case study prep were my weak spots. After a week of daily practice sessions, I walked into my Meta interview feeling like I'd already done it before. Got the offer two days later!
