Now I'm not really a designer... and I didn't hide that fact, but they actually liked me because I was called back for a second interview together with 3 other (real) designers.
In the end I didn't get the job. However, what pissed me off wasn't that so much but that the reason I didn't get it was due to my shyness!
Ok, so I am bit shy and perhaps not too articulate when it comes to verbal communication, but damn it I never thought that would keep me from a job!
I guess there's only one way to go: take it as constructive criticism and do better next time.
But I know I could have done well with that job. Shit!
