The technical part was okay but HR was a mess, they would forget to call or follow up or get back to me. They were a lot of nice and knowledgeable engineer I talked to.

First, there will be an interview with the supervisor and HR, and then there will be a technical interview. After 4 rounds of interviews, most of the interviewers were experienced engineers. The whole process is very professional, but HR will not proactively inform the results.
