Project leader did no work on our project (mainly due to not knowing how to do it), so he dealt with the problem by asking me to explain the entire infrastructure and setup to him five minutes before our call with the Director where he attempted to state all the things that "we" had done.

After his spiel of detail-less crap I explained exactly what was going on, and how I had done it, and the Director seemed far more interested to speak to me.

I'm an intern and the PL has been there full-time for over a year.

I said "I think that meeting went pretty well! He seems happy" after the call and was totally ignored 😂

Intern 1 - 0 Lazy, patronising, rude full-time employee.

TL;DR: If you do fuck all, let the person speak who knows the project inside-out; don't try and get in there first or the hard worker will then go into way more detail than you under to prove their worthiness!
