The more concrete you are about what you want to know, the better. If you lead with, “Hey, how do you think my presentation went?” you’ll probably hear responses like “I think it went well,” which aren’t particularly helpful. Instead, probe at the specifics and make it easy for someone to tell you something actionable. “I’m working on making sure my point is clear in the first three minutes. Did that come across? How can I make it clearer next time?”
