3rd Interview: It was half an hour-long interview with the COO. He was about 15 minutes late. After the intro, he gave me one easy cp question, it was like : * consider you've [1, 2, 5, 10, 20, 50, 100, 200] notes, for an input amount give an output of the minimum number of notes required and what are those? He gave me 10 minutes to solve it. Previously on the last two interviews I wrote the solutions on google docs and didn't have to compile them. But this time, he told me to open my own editor to write the code down and compile it. But that day my compiler betrayed me :p and couldn't compile it on time also I missed a very silly optimization on the code. Even though my solution was correct I had to face consequences for missing that easy optimization. After that, we chit-chat on the same topics from the last two interviews for another 10-12 minutes.
