We all do it at times I guess. I am great at talking about myself and relevant experience but when it comes to explaining the technical stuff I just seem to waffle a big pile of rubbish. Made myself look like a total newb in one earlier. Out of uni two years but couldn't hardly know how to explain oo programming, .net v php comparison/contrasts, whats polymorphism, and explain in detail what compilers are! Only had the weekend to prepare but really made a hash of it! Anyone else do this often and how does it affect the confidence afterwards? I am already in a job so it doesn't make any odds. Just wanted to keep the interview skills up, but i think they got worse that before!
