You’ll feel weird the first few days on the team. You won’t have enough information to make a good decision. You won’t know all the nuances of the jobs people do. You’ll feel a bit shallow in your responses, but you can still win the day. Straight talk is the source of trust. People will want to know if their jobs are safe, and if they can trust your word. Those first few weeks are critical. If you don’t know an answer, say so. People know when you’re bluffing.
