Thank you notes are deceivingly difficult to start no matter who you’re sending them to. Writing them to hiring managers after job interviews is even more challenging. After all, you want to seem gracious, excited, and enthusiastic about a role without going overboard or giving off the wrong vibe. And of course, you have to send one. It could mean the difference between a second interview and a one way trip to the “pass” pile. So how can you be sure to write the perfect interview thank you note every time?
