How would you find out why the API is responding three times slower than a week ago?
Do the interview twice: first with AI, then for real
A voice interviewer asks questions for your role, listens to your answers and shows where you lose points.
Your first interview is free

You answer by voice
Like a real call: no hints on screen, with pauses and a natural pace.
