Let’s compare. I’ve interviewed for and been offered both high paying tech jobs and investment banking jobs. My interviews for tech really required me to have a deep understanding of the technology and how to solve problems with it. They tested my critical thinking skills. For banking, sure there were some technical questions but a lot of it came down to what school I went to, how I acted, who I knew. I suppose either one could be a “nightmare” depending on who you are. I do think the tech interview process was much better at hiring generally competent people. There’s also consulting which I have not directly interviewed for but the interview style is more similar to tech with more of a focus on mental math, those can be very difficult if you don’t have that skill.
