Applied through the university career site and received an email for a phone interview involving coding exercises.

The interviewer was quite demanding, and I could sense that he had already made up his mind to reject me since I failed to provide the most efficient solution for the first technical problem.

1. Describe your background.

2. Given an array of integers, modify the array by moving all the zeros to the end (right side). The order of the other elements doesn't matter.

   • Comment: Asked for the most efficient implementation involving partition of arrays into two and approaching from both ends.

3. Convert a number to English representation.

   • Comment: Interviewer admitted that this is a very hard problem and just wanted to know how I would approach it.
