I had three rounds of interviews: HR - hiring manager - panel (5 people, on site). You'll have to do a 30 min presentation before the panel interview. Most of the interviewers are very nice (especially the female leaders) and mainly focus on my resume experiences, but I do remember one interviewer from the technical team kept challenging me during the whole interview, as I don't have experience in the electronics industry. The work place is newly furnished and I can definitely smell it, and I saw some of the employees do not eat during the lunch time, so I can imagine they work really hard. Overall it's a good experience for me, just be prepared for the workload.
