Name this movie! (I don't recall the name and this worked well last time)

Five or six people are picked up in a van for a job listing on Craigslist (something like that.) They are told to fill out this form and do what they are told and the winner will get the job.

[SPOILERS:]

In the first five minutes the interviewer shoots a guy in the head and leaves the room.

The movie ends with them catching one guy who listened to them all with the idea that the group behind the "interviewing" was the US Government who was orchestrating all the terrorism and bombings and whatnot with people that they found via this program.

[/SPOILERS:]

At the time I thought it was kind of lame, but as a pitch and the way the movie maintained tension was a winner. Its been a while.

Google is fruitless in situations like this.

Help me Obi One Dreadit, you're my only hope.
