Yes, it is very culturally specific so I guess that should be taken into account.
Here (Australia) it's common to have a 6 month probationary period where you can be fired or leave with basically no notice as employee and employer determine if it's a good fit, after that it becomes significantly harder to fire and the employee needs to give a few weeks of notice to leave. So a year is generally fine, you passed your test and were enough of an asset to make hiring you worthwhile and repay any onboarding overhead.
A few 1-year gigs in a row though, yeah, people will definitely ask.
