Nope we mostly come from either state schools of our original residence or small liberal arts schools. I know of two hires from those schools, and I am the one who taught them pure typed FP.

I'm the only one who came in knowing pure FP at all and I didn't learn it via classes.

That's a bit biased. Berkeley and MIT students are pretty pragmatic, and are not typically FP enthusiasts (as in, many aren't even if some are on their own accord). Many European universities have more of an affinity to FP, comparatively speaking.

Err, not exactly, Berkeley and Mit use python now and have been for a while.

I can't speak for MIT but Berkeley has essentially translated SICP material to Python and then you have to write a Scheme interpreter.

Students there have more FP experience than most.

I went to a state College (Mizzou) and everybody I knew that was in a CS degree took a Haskell course.
