What is your preferred method of communication for serious feedback? Do you prefer to get such feedback in writing so you have time to digest it, or are you comfortable with less formal verbal feedback? Why did you decide to work here? What are you excited about? How do I know when you’re in a bad mood or annoyed? Are there things that always put you in a bad mood that I should be aware of? Maybe a direct report fasts for religious reasons, which sometimes makes him cranky. Maybe he always gets stressed out while on-call. Maybe he hates reviews season.
