of course,
1) Whilst arriving at least 2 hours early for a 4 pm interview on a Friday (if poss), survey the fire meeting points ensuring you will be in the right place should an alarm be raised.
(it may be question in the interview)
2) Aim to take a careful note of how to locate the fire points and thoroughly memorize them for at least a half hour relative to your interviewer's location and design a path so that you may easily be in this viscinity later should the alarm call.
3) about an hour and half before your interview set off the alarm and make yourself very indespensable in his/her area including running back for final checks this will ensure that he has a quick thinking considerate professional he is standing next to at the fire point outside, later he will just about to to apologise for the delay when you open the door for your appointment and then he recognises 'you' sitting in front of him with a ripped jacket and dislodged tie looking very cool calm and collected a person who took the necessary time to check the fire procedures whilst the others being interviewed didn't bother.
At this stage as your appointment is the last interview of the day and the previous interviewees will go through ahead of you and you will be last then he will have your memory for the weekend..........
