Unisys Senior Developer interview questions

Interview was scheduled for 8:30 in morning and was told over the call be there even before 8:30. The person who scheduled the interview came to office after 10:30. Interview starts and interviewer looks at the resume asks 4 questions and I answer them and asks are you aware of the job description. All I was told was that it's for senior dot net developer position at unisys. I tell him the same things. N then he asks me to leave. And then recruitment coordinater comes n says sorry u haven't made it to the second round.

Interview was hopeless, I was asked answer a question , how main thread terminates child thread gracefully. I answered that with some mechanism you communicate to child thread that you should stop executing by informing throw request in queue or any other way, then he asked tell me easiest way , i did not answer any thing for that because i felt i have told in a generic way ("i.e. u have to communicate to child thread in some way ) But he was expecting like a global variable which is shared between the parent and child thread. SO i felt he does not deserve to be interviewer.
