Interview process was quite long. The fact that their recruitment didn't read through salary expectations is a very big flaw in dragging people along for the process. I went through 3 rounds of interviews, each round they had asked what my expected salary was.

They ask a lot of technical trivia questions that have nothing to do with the job. They like hearing stories about how you raised the bar and/or made your prior job better. Be familiar with the STAR method.
