Recruiter contacted me on linked in. I had two phone interviews, one with someone who would have been a coworker and another with who would have been the boss. The first interview with the coworker was easy, not many hard technical questions just questions about resume and experience. The interview with the boss had a lot of technical questions related to and extrapolating on the experience listed on my resume.

Phone screen interview lasts for 45 minutes. 3 min self introduction and interviewer shared his screen and asked for answering few questions based on the circuit he draw. The process continues for about 40 minutes and last 2 min for asking questions.
