Worst experience till date. Today I was called for...

Worst experience till date. Today I was called for job interview at 2pm and was waiting till 6:50pm then I left for home. Cos till 6:50pm, not even the first round was conducted. No one even asked for water. If u have whole day to waste and nothing to do then please go through them. When I told this to the Co ordinator, I got this response by which I was taken aback. Which said (All candidates are waiting OK) this was the reply I received.
P.s. GO ON YOUR OWN RISK.
