I applied through a staffing agency. The process took 1+ week. I interviewed at OnApp in Feb 2021
Interview
It was a very nice interview. I especially liked that the easy atmosphere that allowed some nice communication. There was no pressure and I had enough time to think about my answers. The best part: I got a very quick feedback (took less than two days).
