Meta | Phone Screen | E4 | US

I had a phone screen interview at Meta. The questions were:

1. Valid Word Abbreviation - I provided an optimal solution and coded it efficiently. Although there were a few bugs initially, I resolved them during the code walkthrough. The interviewer was pleased with the solution.

2. Local minima (variation of Find Peak Element) - I initially offered a linear search solution, which the interviewer accepted. However, they then prompted me to optimize it. I subsequently provided and coded a binary search solution, verifying its functionality with an example.

I completed both questions within 45 minutes. Three hours later, I received confirmation from my recruiter that I would proceed to the next interview stage.
