I went through a recruiter (who was awesome) who did the initial standard phone screen, after which I had a phone interview with the CEO.
This was followed by two more in-person interviews with the CEO and several senior staff members, including Directors and VPs.
There was no reason for the in-person interview during the COVID pandemic, other than the CEO wanting to prove that the company was 'safe'.
The interviews were really easy and casual. There were no difficult questions, and the talk often drifted away from the position. It was more a personality review than anything else as far as I could tell.
