Phone Interview. A very nice interviewer. The interviewer call me, and ask me some background questions first. Then he gives me a link of Google Docs, and give me coding questions on the google doc, and I need to finish the coding problems.

First I met the engineers at the carrier fair at my school, I submitted the resume. About two weeks later, I got a phone interview. The first interview is just talk about your background and several basic tech questions. The following two phone interviews ask about your projects on resume, some coding questions and machine learning questions. Just one day after the last interview, I got the offer.
