2. The problem isn't the interview, people can show their knowledge in an interview. Problem is getting the interview.
Once you're in the interview, it's more about real experience and knowledge. I think nobody cares whether you got your experience from school or from somewhere else.
That said, without the CS education (formal or otherwise) some fields of work will be inaccessible but I think these are in the minority.
So the idea is to get your foot in whatever door you can at that time, and climb when you can.
This is like the "boomer handshake" meme. Nowadays you need a degree.
Admittedly, this was at a company with about 500 employees and 1 part-time HR person (who quit 6 months later and wasn't replaced).
I've been asked about my education in initial recruiter screens maybe 10% of the time, and its come up later down the line in interviews maybe 20% of the time. I've never had it clearly and obviously preclude me from moving forward (as in obviously dropped from consideration after that conversation).
I've found most people who ask to be curious, but keen to move on and talk about my experience. It might be different at the entry level.
