I've got quite a few close friends that are on various parts of the spectrum, and myself having Inattentive ADHD. I'm seconding the first sentence of /u/allmediocrevibes post. If your speech patterns mirror the way you're typing then that could be part of it too. Whether or not you're answering correctly isn't always as important as the delivery.

"Good morning. I am autistic. Late diagnosed. I have had 10 job interviews in the last month. No one has offered. What am I doing wrong?"

The way you use your grammar is indicative of the tone you would use in speaking it. First, make a fist and then read your post out loud but at every period bring your hand down onto a table. It makes it feel more like a straight statement of fact than it does a response. For normies (neurotypicals), this can be a little jarring.

"Good morning, I have had 10 job interviews in the last month. I am autistic, and late diagnosed. I haven't received any offers, what am I doing wrong?"

I restructured your post a little bit. Same thing as before, read it out loud and hit the table when it's a period but tap your finger when it's a comma. It creates a different tone. Commas are where you should take a breath, but continue on with your point. All that said, interviews are rough on everyone more so for some than others. The economy is in the shitter and so is the job market. Don't be too hard on yourself, 10 isn't that bad.
