Interview started from the basics of neural nets and became more focused on project specific and background specific topics (My background is NLP). Differences between L1 and L2 regression, etc. were asked.

Standard machine learning questions were asked. They wanted to make sure I really understood the topics. All questions were fair and good questions. They also asked me to describe a research paper and walk through it.

I was referred by a friend. An engineer contacted me to set up an interview. There were a total of 4 rounds of interviews, and all of them were half coding and half machine learning.
