Social sides are great aren't they... I went for evening dinner before the interview process years ago. Had travelled over from Ireland to UK, was a bit knackered, had shower lay down on bed and fell asleep.. woke up.. supposed to have been down 15 mins before.. put on smart casual (as the dress code had advised) went to the pre-dinner kickoff , opened the door everyone bolt upright in suits/skirts with pens poised.. I walked in, apologised, and sat down at the one remaining seat right under the head of Personnel (they were called that then).. Within about 2 mins of me sitting down the words "and of course the selection process started from 6:00PM tonight" seemingly telling me.. you've blown it mate. Well I thought bugger that.. ah well there's dinner and a free bar afterwards.. so had dinner, all the empty wine bottles seemed to sit next to my place and afterwards had about 5 or 6 pints in the bar. Stayed drinking in the bar that night till about 2:30. Up next day at 7:00 to be out at 8:00.. cracking hangover, really hot day.. drinking gallons of coke/water/tea to rehydrate. Did the aptitude/competency tests, had my various interviews with the different managers in the company, flew home (ended up staying in a house in Dublin with 7 air hostesses but thats a different story). Thought nothing of it as expenses were all reimbursed and was then very surprised when two weeks later the postman arrived with a bundle which included offer letter and company employment contract/booklet etc..
Moral of the story is to be relaxed in the interview.
