KLA was at the career fair at our college. Got a call for a basic interview. I was asked some basic Machine Learning questions, for eg. the bias-variance tradeoff, etc.

After that, I had a phone interview with the hiring manager. I was asked solely on my resume and past projects.

Then I was invited for an onsite interview. The first hour of the interview was the presentation, followed by 6 interviews by managers from 6 different teams.
