The way to alleviate anxiety is to willingly approach the thing that makes you anxious. Do it in small enough increments that you don’t overwhelm yourself.

As a person with autism (like me) you likely have lower than average working memory. You can expand your working memory by playing Follow That Frog on Lumosity for 60 minutes straight without taking a break.

People will say that Lumosity has no effect but the procedure I described is not the same one they used in the study that concluded Lumosity doesn’t work. Other studies which have used procedures similar to the one I described (60 mins, same game on repeat, no breaks) have shown efficacy.

Be warned that for two or three days after your working memory training session everything will be worse, not better. But once you recover, everything will be better.

What has worked for me and may or may not help you (also lived in Sweden) is that I write down questions to ask and I go through them multiple times. I also write down questions I think they will ask and then answer them in a very thoughtful way so I can later deliver them in a shorter version but till get a across what I want. I also bring the notebook with me so I can read them at the interview or take notes. Taking notes are great if they have a multiple stages kind of interviews.

Also I put myself in the mind set of "this interview is for me and them to get to know each other and get a feeling if this is for me". That kinda removes a lot of the stress. I am there for me and my self and here to interview them as much as they are there to interview me. Also many first check the personality, my current job told me later that after the interview they ask everyone "would I like to hang out with this person". Many good bosses have said "personality can't or is hard to change and knowledge and experience is something you can easily obtain".

So you should also try to see if the workplace you try to be hired as is even a nice place for you to be at. I have so far liked small companies the best with 20 to 50 employees.

I have been on the other side of the table to (not in the room but helped my coworkers and asked them questions about the interview afterwards) and a lot of them are just as nervous or unprepared as the one seeking the job.

My dad told me that he thinks like this when he is holding a meeting for higher ups "they all shit in the same bathroom as me today". I don't know if that helps but it is kinda the same things as I what I tried to say above. Good luck! :D
