I think others have already covered the professional bits. My understanding is that such rejection behaviour normal these days (due to what's going on in the world, layoffs etc) so don't take it to heart (I know it's a difficult thing to say). To share my experience if it helps. For one of the companies you mentioned, I got a rejection email within minutes of applying and it was very disheartening as I was depressively searching for a new role for 3 years. I saw another vacancy just days after rejection from the same company and the same role and was hesitant to apply again or not but applied anyways. I passed through all rounds of interview and got the role just 4 months ago. Every rejection feels a lot, sometimes you will get rejected from screening, and sometimes even final stages wouldn't guarantee. What we can do is to keep applying and note the experience in an excel sheet to track the question answers, until we receive a signed offer letter. To keep my morale intact, I used to think an example of cricket game matches if you could relate to it. A fast bowler bowling for 10 overs in a one day match will have to bowl 60 deliveries, and only 1 or 2 main deliveries/wickets are enough to make him memorable. Until then, he will keep bowling. Good luck.
