3 rounds + Recruiter screen.
1st round majorly on resume and my experience.
The 2nd and 3rd are mostly technical rounds on computer vision stuff. Coding question in Python on coding bundle adjustment algorithm.
Had a great informal chat with the hiring manager via Zoom. Felt the interview went really well and was a nice back and forth of learning more about the company while describing my own experiences. Though then I never heard back after the interview and assume I was unsuccessful after being told I was through to the next round in the interview itself.
First there was a Recruiter Screen
Then a chat Head of People
A technical discussion with the Chief Scientist
Lovely conversation with the CEOs
Pretty standard conversations all around. And everyone was very nice.
