I have to agree with this, sadly. Before I got my current job I went to over 10 different interviews for tech startups where I live every process was the same. It was torture to go through these, and keep in mind at the time I was just getting into college this was going to basically be my internship. The questions were absurd and just completely out of place for what I applied for. I felt like I was going in for database management or just general software engineer when I went in to be a website designer. It’s discouraging going through these interviews because you question your own self worth (as OP said) which makes you want to stop working in the industry.
