First step: 45min presentation with the principal investigator. Second step: One month later, the PI emailed me back and ask me for two references. And Spoked with my referees the next week. Third step: two weeks after I emailed my references. Had a meeting with HR about benefits and salary. The associate level salary range is 60k-70k. The HR said her camera had some problems. So I was the only one who turned the camera on and it was a really awkward experience cause I didn't know where should I looked at.
