I applied online and was provided a coding challenge a few weeks later. The coding challenge was difficult but doable within the allotted time.

After the code challenge, there was a technical interview with one of their software engineers. Right from the get-go, the interviewer wanted to know if I really knew my stuff. They asked questions on algorithms, questioned the methodology on past projects, and tested the rigor of everything I said.

Next was the online coding portion of the phone interview, which was probably one of the hardest interviews I had done. This was partially because I had forgotten a lot about linked lists. I had an idea of how to do it, but couldn't finish it in time.

Convert a tree to a linked list.
