About 15 years ago I managed a software team and decided I wanted to consider new opportunities. I wasn't sure I was leaving, but I wanted to see what was out there. A recruiter saw my resume, called my workplace to speak to the hiring manager, and offered his services to help the company fill their soon-to-be-vacant development manager position.

The recruiter was happy to reveal that I was considering leaving until he realized I was the hiring manager he was talking to. He quickly hung up.
