Applied online. First stage was a short virtual interview with HR. Second stage was a virtual interview with CSO/CTO and evaluated my scientific background. The final stage was an in person interview with CSO/CTO involving a case study presentation and technical / motivation questions. The team were friendly. However, I never heard back, not even with a rejection email. I followed up by email but still never got a response. This was very disappointing, especially since I travelled for an in person interview.
