Most employees are hired as external. The 1st interview was a screening with the eternal agency, the second with a direct recruiting manager. She actually didn't hire me but recommended me for another team, so I was contacted by another recruiting manager. This confused me a bit but I went on with it and it was worth it. After that I got a technical test to prepare and a time was set to present my work, to the manager + my direct co-worker. Lastly i had an interview the the HR. The process was nicely handled, in a friendly atmosphere. I had covid in the middle of it so could not meet them in person, only by zoom.

short Phone interview, long phone interview with team lead, home test (three days, including four different tasks), review of home test with team lead and experienced worker, interview with the team manager
