There are two such movies that I was once aware of but have since forgotten their names.
Both movies are kind of psychological thrillers where a handful of people answer an ad for a job and go to an interview.
The people are placed in a room and the interview is extremely mysterious and even “creepy”. They are not made aware of all the rules for the interview and have to “guess” as to most of the correct answers and even to the questions. Very strange and creepy indeed. I do recall that in one of these movies, one of the leading characters gets shot near the end.
I know the name of one of these movies. It is “Exam” from 2009.
But, I don’t know the name of the other one.
One of the nice things about IMDB is that when you look up a movie, there are a few other titles at the bottom of the page and it is stated that people who have looked up this movie have also searched for the following movies. But, unfortunately, that did not help me in this case.
