Never, EVER sign a contract without reading it first, and having your lawyer review it.
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
Never, EVER sign a contract without reading it first, and having your lawyer review it.
That presupposes that people have a lawyer, and one specialized in employment law at that, which is highly unlikely to be the case for 99% of the population.
I never did, though. I just crossed out the clauses I didn't want to accept and initialed them.
