Saxo Bank interview questions

They got back to me 2 months after I applied. First call was an introductory meeting with the manager. Then they gave me a design assignment - which was supposed to take 4-6 hours but since it was a full redesign it took much longer -, which 2 weeks later I presented to the manager and another team member. The interview felt a bit awkward and the vibe was different than the first one, less friendly. Anyway, 2 weeks later they let me know they have decided to proceed with other candidates. So, in total, the process lasted almost 5 months.
