I was reading a new book that came out recently, called "13 Things They Won't Tell You". It is a compilation of things that people in various professions expect of their clientele or employees but are more unspoken rules. It covers auto mechanics, hairdressers, hospitality staff, and most importantly for the context of the work category I'm posting in, what HR managers won't tell you (but expect you to be aware of). I'd HIGHLY recommend this book as a helpful guide.
A lot of these things are the "common sense theory of mind" pitfalls that we so often run afoul of.
The HR manager who was interviewed by the author spoke in the 1st person as you can see. A paraphrased sampling of some of the tips:
1) If I ask you "tell me about yourself" in an interview, do not ask me for specifics. I don't need to hear your life story either.
2) Some jobs have a rated requirements or scorecard to rate candidate answers to questions, particularly factual ones to test ability to perform a task. Well I can tell you that many times this doesn't matter; I personally saw a hiring manager doctor the responses just so that she could hire the candidate that she liked. (Well, this should come as no surprise - I'm sure it goes on more often than we'd like to think, and I can think of at least one instance where it happened to me.)
3) If you boss calls you in his/her office to say that you're being let go and he/she says "I'm sorry, but they made me lay you off, I really wanted to keep you" i.e. deflecting the blame to other management, you can be almost certain that he/she was the one who made the decision and their statement is totally false. (a lot of the time we Aspies won't sense this, as we don't perceive the more subtle emotional cues that somebody doesn't like us or isn't pleased with us)
4) If you call in a couple of weeks after your interview asking for an update, and we say "we have no update yet", it's almost invariably because we've chosen our preferred candidate(s) but that person just hasn't accepted the job offer yet, so we don't want to reject you prematurely. (I actually always suspected this was the case, and I spoke with a job counselor who confirmed its veracity.)
5) If the hiring manager goes on about his hobby or interest, let him talk about it all he wants, even ask him a couple of questions. At the end he'll think that you were the best candidate, as long as you didn't give horrible responses to the job-related stuff. (Kind of a double-standard considering that we Aspies are blamed for going on about special interests...but hey if we're not holding the key to a job...we're the "bad guys" I guess.)
Of course there's the other "common sense" stuff about not trashing a company or your boss on Facebook, and not using social media and email etc to look for work on company time (or for leisure, for that matter) - mistakes that many NTs make!! Makes you wonder why companies have such a positive bias towards extroverts, when they're the ones who're more likely to be surfing Facebook to get updates on their 500+ friends (slight exaggeration).
