It was a phone interview for about 45 minutes. The position was on software testing. The questions included sliding window protocol in TCP/IP, congestion control, how to access a file in unix, definition of database schema, diff between white box and black box, what is JUnit testing, what is automation testing.

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.
