Relatively straightforward interview. First round screen, then second round panel, then final round with director. Asked questions about background, experience. Then went on to some more technical questions, like explain specific ML algorithms, experience with them. Ended with share screen of SQL + Python ML question and asked to explain and find errors. Interviews felt rushed.

I thought the questions were fair. Basic questions about stochastic processes and queuing theory. Make sure you have a background in understanding probability and strong queuing theory, and you will be fine.
