How do you get over a bad internal interview?

To get over a bad internal interview, you should first take some time to debrief after the interview and then send thank-you notes to your interviewers. Sending thank-you notes will give you an opportunity to clarify any questions you might not have answered as well as you would have liked.

After that, you should avoid over-thinking about what went wrong. It's important to keep your job search moving instead of being stuck on what went wrong.
