What question in particular do you find not appropriate?
In my opinion, the so-called 1 on 1 meeting should only be used when an employee is clearly on the wrong trajectory and a course correction is needed.
Good feedback is difficult, what I've seen was very often high noise and low signal. Forcing feedback when not necessary will not lead to added value for the company, only mildly boring and stressful waste of time, in the best case.
But not before.
Feedback comes because you’re talking on a regular (weekly or bi-weekly) basis. If the employee is on the wrong trajectory, you’ve waited far too long to talk!
