Nieces

So I'm a night owl and was just completing an online video assessment / interview for Sky Retail. Felt I answered the first of three questions really well and was going well on the second question which was about how I dealt with setbacks. More or less during the last minute of a 3 minute time length an alarm starts going off and I clock it's my nieces (who's fast asleep upstairs). No idea of her passcode so the only thing I can think of doing is moving it to the next room and closing the door. I style it out by saying "well that's one way I deal with a setback" making a light hearted joke about the situation but I feel like this happening has most likely messed things up. Am I screwed or did I style it out ok?
