I applied through an employee referral.

• 1st round - chat with recruiter, they tell you all about the interview process.
• 2nd round - coding interview. It was a simple research based question around a simple algorithm (NMS). You talk through it and they mark how you're doing occasionally offering advice.
• 3rd stage - 1 more coding interview same as above (this time it was some navigation algo). 1 interview on AI knowledge - very basic questions but they want you to be very clear with your explanations, it was the kind of stuff you studied at beginning of uni, and have probably forgotten already.
• AI design interview - you go back and forth designing a product. They expect you to be very detailed (but they won't tell you 'be more detailed', I got this from the feedback).
• 4th stage - I didn't reach.

Tell us about your research.
