Process
I went through two phone interviews.
I am still in the process, but they told me that my next interview would be for a trading position.
The interviews lasted for approximately one hour. We used a Google Docs-like service to share code.
Although I was told the interview would be regarding OCaml, I was asked to pick a language during both. I chose Python.
