The best onboarding experience starts before a new hire’s first day. The week before they start, consider sending your new hire a welcome letter with information about what their first day will look like, expectations for what they should bring on that day, and additional details they might need to know—like the dress code or lunch policy. Once your new hire begins working on your team, make sure you’re available to walk them through the onboarding process and answer any questions they might have. Consider assigning them a mentor to provide a peer relationship and support, as well.
