Technical Behavioral
Started with a recruiter call. Then had a call with a Senior developer. He was late for the interview and didn't turn on his camera, even though the recruiter had asked me to record the session. He spent time going through my resume and then left me waiting on a blank screen for 5 minutes. The questions he asked seemed to expect me to guess his thoughts. When I tried to clarify or discuss a question, he would abruptly change it mid-way. After about half an hour, he just ended the interview.
