Most positions with comparable salary to software dev involve interviewing with a hiring manager, a VP/director skip level, and usually a ‘behavioral’ interview which is often with an HR person. Take-home problems like doing a competitive analysis or preparing a presentation are common.
The big difference is, for a position in a softer nontechnical role, there aren’t any remotely objective criteria the interview can possibly assess you on - if you hate being tested on your technical skills, consider the alternative: being asked fuzzy ‘tell me about a time when..’ questions, and weird ‘if you were an animal what would you be?’ popquizzes by an amateur psychoanalyst who thinks they can get deep insight into you by watching your body language.
You also get judged a lot more for your looks in nontechnical roles. For example, if you're doing sales, simply being attractive could be a huge advantage. It makes sense but it also sucks if you aren't in that category.
What other professions have a standard lengthy process with multiple rounds of interviews even for interns?
