I don’t understand this view. Learning to “game the exam” (by which you mean pass) is the gateway to all careers, whether you’re a truck driver or a brain surgeon. What’s special about software?
Brain surgeons gets sued and you get a public paper trail when they do a bad job. Also they often have a lot of data of all their performed surgeries they can refer to. Software engineers however fails silently and nobody will know. Lawyers, the other big profession that are paid a lot, also have a lot of data they can go by to prove that they deliver value.
Can you give a single profession that pays $200k+, isn't a manger job, doesn't have easily tracked metrics like doctor/lawyer, and doesn't have tests like the algorithm interview?
What if the accreditation for this industry is simply do the existing LC exam, except once you pass it you're good for 5-10 years until you renew your license? Instead of the current system of having to retake it every single time you change jobs.
