Started with a call from the staff recruiter. I was asked what I wanted to work on & what I had worked on in the past year. Next I was asked a question by a senior engineer. I was asked a question related to trees. I used Ruby to answer the question. I needed help, but eventually got it. Maybe the interviewer provided too much help, I dunno.

Basic engineering/algorithm questions. Write the codes in a collaborative coding console. at least two coding questions and one design question. Culture part is designed for me to ask any questions related with team and culture. After the interview, the expected wait time is less than 2 days. I accepted the offer immediately.
