I had two rounds of interview with the team members. One for programming which is medium level question and the other for general machine learning questions including big data, data imbalance etc.

One phone screen, followed by an onsite interview. The phone screen was 1 hr long, asking signal processing fundamentals. The onsite interview consisted of 6 rounds. The first round was a research presentation. The last 5 rounds were one-on-one discusstions about the background, signal processing and machine learning knowledge, behavior questions, and coding.
