The interview process includes a technical presentation, and interviews with chief engineers. The interviews were easy asking basic work ethics questions. The process seems more like onboarding process. The chief engineers (there are 4 engineers) are elderly people and the process was old-fashioned with in-person interviews. During interviews, I felt like they were hiding something from me regarding job responsibilities. I had received the offer after 4 months, and I accepted it. Later, they pulled back (revoked) the offer. When I talked to former engineers, they said that they were laid off due to financial issues of the company.
