I have Asperger's and have major issues passing job interviews. In the past I have had a large number of job interviews (haven't kept count but probably somewhere between 60 and 100) and failed all but one. I have had plenty of different jobs over the years but almost always got them by passing some test, going through an agency without interview or being referred to by someone.
One way I have tried to get round the interview issue is building up a large amount of academic qualifications to try to outdo the competition and try to dampen the effects of my poor interview skills.
All the usual interview technique stuff I'm generally aware of - prepare answers to anticipated questions before hand, try make eye contact, try build rapport with interviewer, be presentable etc.
Knowing that and putting it into practice are two different matters though. If I can say something awkward (very often honest words) in an interview, I almost certainly will - by accident. I struggle to come across as presentable and I tend to have a blank look on my face, look distant or unenthusiastic about the job/interview (I'm not unenthusiastic, I just dont show it well, I'm definitely not a good actor/salesperson). I've had plenty of feedback about this before and do my best to act on it.
This stuff I'm well aware of and try to do what I can to deal with it, but after so many failed interviews I just accept my brain is never going to handle this situation as well as most other people out there, as much as I try. I am not put down by this and do what I can to try improve on each interview, but accept that my ability to deal with formal social situations are limited and do not expect to ever perform well in this respect for the rest of my life.
The question I have is how to try get this point across to interviewers beforehand without it making the whole process awkward before it even starts?
I don't want to sound rude or arrogant to the interviewer, but how much eye contact I make, how well ironed my shirt is or the tone of my voice sounding blunt and plain has little to do with my ability to do the sort of technical work I'm applying for (which is much better reflected by qualifications I have, the references I can get etc). Unfortunately the social stuff/personal presentation in interviews has a huge bearing on getting the job, even if it has little impact on my ability to do the work well (depending on the job you're applying for obviously). At least giving them a heads up that a glazed look in my eyes etc is no reflection of my eagerness to work at the company.
I'll point out that I have looked through other similar questions on here and they almost all recommend NOT pointing out Asperger's/autism at an interview. However I think at this point I have little to lose by trying, so I'm not asking whether it should be disclosed or not, only how to do it in a reasonable way.
