Companies don’t really need non-competes anymore. Some companies take an extremely broad interpretation of IP confidentiality, where they consider doing any work in the industry during your lifetime an inevitable confidentiality violation. They argue it would be impossible for you to work elsewhere in this industry during your entire career without violating confidentiality with the technical and business instincts you bring to that domain. It doesn’t require conscious violation on your part (they argue).
So beware and read your employment agreement carefully.

And this is the insane legal doctrine behind this
As the employee, it’s still clearly a bad position for me unless I can find a non-competing job that pays me at least 70% plus whatever pay bump I’d expect for career advancement.
This clearly depends on your role and industry. I can write code in a bunch of industries I've actually never had 2 jobs in the same industry. If I were an oil pipeline engineer it would be different.
