Urban Company Software Engineer, Backend interview questions

I applied online through their job portal and was contacted by the HR to come to their office for the further process On the first day, the process consisted of 4 rounds. 1st was a written round with 2 problems. 2nd round is a technical rounds with basic level of questions. You are asked to code the solutions on paper 3rd round is a technical round with higher level of difficulty than before. Pen and paper based again 4th round is again a technical round. This round was more of a discussion round with open ended questions. Very nicely taken round, thoroughly checking the fundamentals These 4 rounds took the whole day to finish. 5th round was taken after 2-3 days and is also a semi technical round with the vp of engineering, which involved discussion on past experience and projects. The interviewer was busy in gym and came around 30mins late. The start of the interview, was all about him flaunting his experience and work. After that there were a few past projects based questions and 1-2 technical questions After the interview, I was told there would be another round with founders, but was never contacted. I had to call the HR to ask about the application Just a note, that after spending the whole day for the process, an email with rejection reason would be nice and do justice to the aspirant
