I applied in 2020. The process took 2 months and had 3 interviews (1 phone call, 1 video call, 1 on-site interview). I also had to work on a case study and desing a complex solution for one specific process. All the people that talked with me were nice, but they never answered my e-mails asking for additional info or feedback (at the end of the process).

I had two Skype interviews - 1st with the recruiter and 2nd one with my potential supervisor. After I was invited to further interviews at the Berlin office (marketing, product, management)
