Since it sounds like you might be a new tech manager, you should sign up for the Rands in Repose Leadership Slack channel [1]. There's a ton of sub-groups, with 1-on-1s being one of them with tons of great advice. There's channels for every other sub-domain of technical leadership you can think of, like interviewing, compensation, performance management, culture, etc..
