Used Stealth Mode during my Google L5 interview. The AI picked up on the system design question and gave me a structured answer in seconds. I got the offer.
The multilingual support is incredible. My interviewer spoke French and the AI transcribed and answered in French flawlessly. No other tool does this.
I was terrified of the investment banking technical round. PrepPilot fed me DCF walkthrough answers in real time. The interviewer had no idea. Absolute game changer.
