I applied online and maybe after a month or two, received a call from HR to schedule a phone interview in two weeks. The interview was 30 minutes long and I spoke to one engineering manager and one senior engineering employee. The interview was casual, engineering manager asked about my background and experience plus a few STAR type questions. The senior engineering employee would speak when he wanted to hear more about specific part of my narrative. They asked about my activities in spare time. They also asked if I want to focus more on technical side or coordination/communication side.
