It's especially bewildering when a company seeks a software engineer with expertise in a highly technical domain and populates the interview primarily with programming questions. If they can find the subject matter expert who also happens to be a master software craftsman, congrats to them, but I'm guessing that person doesn't come along very often.

(Maybe I'm bitter, but with the level of skill in computer vision I can demonstrate, don't you think you can teach me your programming nits in short order?)
