There were three rounds after the recruiter screen.

First was a coding/design round. Second was a hiring manager round. Third was a design + LeetCode-style round.

In the third round, there were two interviewers. I believe one was shadowing. The main interviewer came late.

We started with an ML design question. This was so out of touch from ML, I don't even know how he was senior ML at Comcast. Anyway, he kept combating and interrupting me the whole time. At one point, he suggested using information gain as a loss function in a neural network.

Anyway, then there was a LeetCode-style question in the second half of the round, for which he didn't even consider giving two minutes extra, even though he joined late.
