Technical Interview:

I was given a test on HackerRank. It was a paired programming session where the project manager helped guide on any issues I was having. He was nice enough and gave a professional interview.

I've read on Glassdoor; it's a similar test every time.

I was asked to code up a Multimap class that inherited from a generic interface of key and value. I eventually got the answer with all unit tests passing.

I was also asked about Big O notation and how to optimize the Multimap.
