> I'd say I had a 10% offer rate. The most common "why didn't you select me?" follow up answer I got was "we need someone who is an expert in XYZ language." I would think this is something that should have been made clear from the get-go in the initial technical phone interview. Anyone who goes to an in-person interview should expect, at minimum, that the interviewers have done their homework. For example, if they just want Stanford or MIT grads, fine. But to bring someone into an interview - which may involve more than a day of travel, lost vacation time etc - just to tell them they went to the wrong college afterwards, that's plain infuriating and shows complete lack of courtesy.
