They use behavioral interviewing as their standard. Questions like, “Tell me about a time when you worked as part of a team and one of the team members was not contributing. How did you handle the situation? What was the outcome?” The best way to deal with those questions was to use the STAR method. Tell them the Situation/Task (the circumstances of the event/ task you were assigned), your Action, (what you really did, not what you should have, could have or would have done) then give the Result of your action (how it turned out in the end). Some of the questions ask specifically for a time when the result was bad. With those remember to add what you learned from the negative result to avoid them in the future.
