You failed to read the interviewer's mind. No job for you!
I really despair every time I read these interview threads. The number of hoops you have to jump through, the questions that require "just so" answers (I'm a 8 out of 10 will get you a fail for being too overconfident by some, and a fail for not being high enough for others), measurements based on everything BUT the one thing that matters - on the job performance, interviews where all information is hidden to the applicant.Take this article: you dragged me in, forcing me to take a day off with pay, and only then tell me the actual requirements of the job? Thanks. Why didn't you put that in the job description, an email, or tell me in a pre interview phone call? What a waste of time.
