Intel's job application site has been a thorn in the sides of all humans for years now.
This is what you get when a company's culture systematically pushes bright, technical people out, and retains sub-standard "talent". The horror stories I could tell you...
Intel took an out-of-box (as they call it) product that had very limited customization features, and forced it on the world. This decision was a group effort: people who had no business making these decisions...made this decision.
There were so many problems with the job application software that entire tutorials had to be created. Imagine wanting to apply for a job and having to read a tutorial first!
Intel is a bureaucracy where mediocrity is much more valued than real talent. This is why the job application process is so bloated, so burdensome. You have an army of proverbial non-technical idiots making technical decisions.
