Notice periods are much shorter during probation periods. It might kick up from 2 weeks (within probation) to the 3-4 months the day probation ends.

There’s no progression in between.

Of course, for serious work, notice periods of 3 months or even longer make sense. But those levels should only kick in after several years. If you’ve been with a company for only a year, there’s no point in a 3 month period.
