Initial screening had a short coding test as well as discussion. Then I had 3 technical interviews from different areas of expertise. Did not get to the HR round. There was no show on one interview. The scheduler did not respond to any of my emails but suddenly rescheduled after a week. It looks like the interviewer cannot contact interviewees without joining the call first.

Fairly simple. Asking about previous experiences and familiarity with different computing languages. Level of difficulty for the coding interview is medium and easy in lc. But does require you to understand some knowledge on operating systems.
