I like the fact that there's so many interesting things that you can learn in the tech industry. On the other hand, I really feel this pressure to know so much just to be able to pass a job interview and get a good job that you want.

I can't think of any other industry right now where the interview process can be quite an ordeal. I mean, sure, there's some general tips on how to pass an interview, but for this industry, you can literally find courses JUST for doing software engineer/developer interviews.
