Someone said :
Just did an interview with a educational institute and I had assumed it would be competency based interview. It was a complete mess, they asked the most vague questions and then the most specific ones that you would only know if you worked there.
And I was right, the receptionist showed me the names of other people attending the interviews (so I could tick off my name) and a quick Google tells me all the others work there.
I had an interview last year that they told me would be competency based, but wasn't. Pissed off is a mild statement of my reaction.
