All participants either late or ill prepared. Interviewee expected to take written test with problems from high school physics. Multiple rounds with people with very poor English skills. Overall very poor

3 rounds of phone interviews. First interview was with HR, then the hiring manager then coworkers. The first round was just a preliminary interview just to get a feel for your background. The second interview with the hiring manager who was 20 min late, also asked background questions. The final interview was a quiz which was hard as its a visual quiz over the phone. In addition many of the questions were from physics (IE final velocity and momentum equations)
