Domande di colloquio per Java Developer presso ABC

there is a on site interview on gurgaon loaction. they call us at 9 am. when we reach on that time there are no interviewer or no any employee are there. and then they come at 11 am and said to wait and after of 2 hrs interview was start and that was my worst interview ever. they didn't ask about what they mentioned in description they ask all the question out of that( vacancy for core java developer but they asked questions on advance java or advance sql).
