I applied via Referral and was interviewed in Sep 2024. There was 1 interview round.

Round 1 - Coding Test 

It was for 40 min. I gave my intro and my career history. Then I was asked a couple of python questions: what are Dunder functions. Then I was asked to do a python coding challenge, which I was not able to solve.

The interviewer did not introduce himself, nor did he mention his name in the zoom call attendee text. His camera was turned off and he disappeared after giving me the problem. I tried to get his attention and he kept saying that he'll be back in a minute.
