Completed phone screen.

For the first round, the question was fairly trivial. I believe there are 3 parts to it, and if you don't complete all 3, then you're automatically disqualified.

The interviewer was a staff engineer and hard to connect with. They couldn't even answer "what is the company culture like". The person said, "I'm probably the worst person to ask"... what a red flag.

Maybe it was a one-off, but still.

Definitely pick a language you're comfortable with to write code and unit tests. The interviewer was basically mute the entire time, even when you're trying to show off a bit of collaboration.

Given a string of accepted languages from a request header and an array of strings of languages supported by the server, return a list of languages that will work for the request.

This involves three parts:

1. Basic matching.
2. Language-only strings without country codes.
