-Those tests are no joke, but saying they are more intense than a 4 year CS degree is ridiculous. Also the major airlines you can compare to FAANG, and many people study for 6+ months to pass those interviews - Airlines are union jobs. If you get them you aren't getting fired unless you try to do something really stupid. - There isn't any wondering if you are doing a good job or not , and you don't take any work home. - Regulations change or you can switch planes, but the career is leaps and bounds more static then SWE.

Net net is that they are very different jobs. SWE is a great gig overall but I take issues with people saying how much harder or easier it is than other jobs. "It depends" is the answer.
