I don't know if Matasano is a nice place to work at (well, friends there have been happy, so I guess I do have some information), but it sounds like a wonderful place to interview for. Enjoyable instead of actively painful and stress-inducing.
If someone doesn't make the cut, what does Matasano say? Do you say what didn't work out, or is it the industry standard and horribly antiseptic "we have decided not to move forward at this time"? I'd understand the latter, but if there's a place breaking that mold, I think it might be you guys.
That sounds fantastic. The few times I didn't get an offer from an interview (early in my career), the "we can't tell you more in case you sue us" answers to why I didn't get the job were as crushing as the actual rejection. I always felt terrible having to give that answer when I worked for a big company, particularly for the marginal candidates. The terrible candidates aren't going to be able to improve enough to game the system, so there's no real risk to giving them the information as well.
