For variety, you can do your 1-1s as walking meetings, or over coffee or lunch to get out of the office. Just remember that when you’re not taking notes you’ll probably forget some important things, so try not to rely on these for critical conversations. Many of us have overstuffed office spaces with very few private conference rooms, but as much as possible, do your 1-1 meetings in private so that you can feel free to discuss sensitive topics without worrying about being overheard.
One final piece of advice: try to keep notes in a shared document, with you the manager playing note taker. For each person you manage, maintain a running shared document of notes, takeaways, and to-dos from your 1-1s. This is helpful for you to keep context about what has happened, and is useful for remembering when and what feedback was given. It will also be an essential historical record to refer to when you’re writing reviews or delivering feedback. If you’re distracted by having a computer open in front of you during the meetings, just leave time at the end to add notes.
