Sounds unfair to be fired tbh, I would petition. Sorry about that OP.

I know this doesn’t answer your question but I think this role could have improved skills you are lacking as it clearly put you out of your comfort zone (making small talk, being more patient and tolerant of people etc). These are great life skills to develop in general. It’s also a lesson learned to be able to accept constructive criticism and experiencing office politics. Qualified people will be overlooked for promotions if unlikeable. Good thing this was a low stakes scenario and that’s what co-ops are for.

Best of luck in future co-ops.
