On my EJ MPL interview:
Interviewer (referring to the team assessment earlier in the day): So, earlier in the day your team failed to build the bridge as required. Do you feel your teamwork failed?
Me: "I believe that we still used great teamwork despite not achieving the final objective"
*interviewer smirks*
Interviewer: "What about if you were FO, and through a series of errors together your team reached the wrong destination airport. Has your teamwork still failed then?"
We both laughed it off as I had clearly dug myself in a hole - really enjoyable interview overall despite going very red after the above
