I received a problem to solve ( I had 48! hours for that). Because I did it at a level they were ok, we had a 2 hours discussion based on my solution

Technical round. Many technical questions fired quite fast at you with multiple assessors. Then coffee solution, takes 3-4 hours. Was delivered late and I had limited time to complete. Afterwards rejected with no real feedback, just "preferred other solutions". Candidates time is not respected, do not recommend.
