Sorry to come back to this thread so late. But I'd like to add that I find Jane Street's sober, mature view to be very attractive. Not the usual pastel-coloured-hype you get from dotcoms, or Button-down-idiocy you get from corporate work but a very appealing no nonsense intellectual approach.

If I were looking for a job they'd be in my top 10. That is all, carry on.

I've given talks there and Jane Street is awesome. Just my 2c.

At about 29:30 "You basically can't pay people enough to carefully review dull code."

I found that very insightful.
