I applied through other source.

Engineering director contacted me through LinkedIn. Called for five round interview after the first in person interview (I requested for in person interview). Most of the interviewers were good. The final round was a horrible experience for me. The interviewer mentioned he is a manager and came with a shadow interviewer. Gave me a question which is similar to meeting reminders in outlook. Asked me to write clear code that could is compilable. Stopped me when I was using a hash library. Not sure why he got so much pissed with that. Could have gently requested me to not to use it if he wants me to avoid it. I mentioned, I will implement the hash library once the algo is written. He didn't like my suggestion and told me to implement the hash algo first and then use it.

Somehow managed to do it in the given time. I explained my idea with a heap and a timer kind of solution. He didn't get the idea. Tried to explain, still didn't get it. Told me that it wont work, explained again. Yes, he didn't get it again. The junior shadow interviewer was giggling as he too failed to make the main interviewer understand the logic. I was happy in the end as I know for sure he was not happy and they will not proceed to the offer. I didn't have to work with that kind of guy who was angry during an interview process. A smile on CEOs face would be helpful (not a necessity though). I saw him through the glass door when I was waiting in the interview room. Smiled, and he didn't return the smile. Gives a very unpleasant feeling.

Some from Leetcode and then some from Leetcode :-D
