5 years ago, I had an interview with Jane Street. At that time I was interested in functional programming but not in OCaml. I think I had a fair chance but I bombed a technical interview. I do not have a "prestigious college" background and at that time I only had like a year of PHP experience. The interview format was also quite good.

I am not sure if the software they are writing is "elite" but OCaml is raising the bar a bit higher.
