Backbase Senior IOS Engineer interview questions

I applied online. The process took 4 weeks. I interviewed at Backbase(Amsterdam) in Aug 2021. The interview process was fast and nice. The recruiter that I worked with was very polite and helpful throughout the whole process. The recruiter was always keeping me informed of the next step. Round 1: HR Interview - Clearly explained the role, interview process steps. Round 2: Take home assignment Round 3: Technical Interview - 1 hour detailed interview with a senior team member. Round 4: Cultural Fit Interview - 1 hour interview with my team manager and PO. It was a chat for checking if I match the Backbase culture.
