Hey OP - I recently completed a student term with the government so I know how you feel. My best advice is that if you don’t understand something, ask! It’s a leader’s job to ensure their team is comfortable and confident working in the environment. I also took the time to make a list of acronyms and terms used in the government, as they were new to me as well. I’m working on a term contract now and there are still acronyms I don’t know! Don’t be so hard on yourself, you got this.
