I had a phone interview about an hour and a half ago with a recruiter for a Summer internship and the person who would be my boss if I were to get the job. The recruiter was the one who contacted me, so I have her email, but she didn't mention that there would be someone else involved until I was actually on the phone with her. I know his first name, but not his last name or his exact position.
I found someone who MIGHT be him on LinkedIn, but I don't want to accidentally send it to the wrong person, especially since I'll have to guess the email.
Would It be rude to just send a thank you to the recruiter? Should I just not send a letter at all?
