I got fired and hired in the same day.
Why would you compare these two events?
I messed something up and was fired for it.
You should be more careful and follow rules so you don't get fired. Be more careful next time.
I don't regret it. Do you think they will wanna hire me again?
If they already fired you, I don't think that the company will hire you again. Don't you think you should just try to look for a job elsewhere and do your best to not get fired again?
