I can't share the questions but let me explain my experience.
It was started at 10:00 AM and finished at 3:00 PM
1st Coding Interview: I came up with O(n) solution and in code I have a bug but I consider it was well explained and 80% scored.
2nd System Design: I explained the answer in detail and with flow diagram, so first Breadth Wide and than in Depth one of the module. It was very good.
3rd Soft Skills: I was very good in explanation and with proper situational answers. (I felt, I made few answers in a way that sounds not having leadership quality)
< Lunch Break>
4th Coding Interview: I came up with optimised solution using Sliding Window and completed the code and it was awesome.
5th Coding Interview: I came up with mathematical solution and it results in O(1) and wrote test cases and explained super awesome.
I was so confident that I would get this oppurtunity.
But next day got the call with NO and they never explained what area was week. Well, after in depth analysis I think behavioral questions give wrong image or first interview with one bug cause rejection. Still, I have the feel that I performed really good in interviews and my efforts was not in vain.
Better Luck next time for me :)
