There were multiple panel interviews. It started off with a phone screen and then a couple other rounds. They asked the typical questions about experience. They were very interested in health and safety.

First, phone screening by the HR. Last for 11min with simple and typical interview questions, such as why do you apply, what's your career plan. Then, only several days later, I was informed for a phone interview with the recruiting team. It lasted 30 min, 3 interviewers. Most of the questions are based on my resume. Besides, they asked something like what's the difference between working for government agency and company. Again, less than one week I was at the on-site interview which should be the last round for this opening. I was interviewed by 6-7 people at that office, through office head and staff engineer. At the end, the chief said something about comforting me. Then I realized I was there maybe just to be a sacrifice for there hiring ppl ratio. They must already had someone on hand by then. Disappointed. But still, it's a good experience.
