The HR department was totally chaotic and unresponsive. Firstly, they didn't schedule the interview until I called them for an update. I lost count of how many times I called.

Then the interview was postponed twice because the interviewer did not show up at the scheduled time. Finally, after so much hassle, I got to give the interview, but they don't have the basic courtesy to respond with the status. It has been over a month.

Normally, I would have assumed that I didn't get through, but with this level of irresponsibility, they might have never even taken feedback from the interviewer.

The only bright side is that I enjoyed the questions in the interview. It was probably one of the most elaborate interviews at the screening level.

Unfortunately, I can't recollect the exact questions as it has been more than a month. I will update the post if and when I remember.

There is a notepad that accepts only four operations:

1. Character X (to type a character)
2. Select all
3. Copy
4. Paste

Given n operations, provide the sequence of choices that yields the maximum number of characters in the notepad.
