applied online, got contacted by HR and talked about the background and the position, then have 45mins video interview with shared screen. The interviewer was 5 mins later and not focused on the interview, he seems wanted to end the interview because he got tons of things to do.

The first interview is a 20-minute phone interview with the recruiter. There are 3 more interviews, so it should be 2 + 1 + 1 hours. Talked about the salary expectation, asked about what the most important aspects are in a work I think.
