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.

It doesn’t require conscious violation on your part (they argue).
So beware and read your employment agreement carefully.
