Contact all the people you loved at your previous job(s) and the people you hated. Contact the people you met once and admired. Contact someone at a company you want to work for.

This is time to put everything as water under the bridge. Ask for their feedback and what you can do to improve yourself.

Now this takes a lot of swallowing your pride. I admit that I wasn’t able to contact everyone and hopefully I will in the future.

At least though, it’s a good way to name drop in any future interviews.
