Oooh poor you, assessment centres are awful. Everyone trying to show they're the most amazing and have all the ideas....
I don't perform great in those sort of competitive groups, so while they note I have all the correct answers, they also note I'm not great at pushing myself and opinion onto the group.
Generally, in interviews if involves a presentation, I speak at the speed of light.
For example, had a 10 min one, practised it at 14 mins, actually delivered it in the interview in 9... without actually cutting anything.
Worst interview though...was scheduled for 9am, as I had work later in the day. Place was about 25 miles away from me in the centre of MK. Found the area it was in but could not find the building or where to park...wasted the whole 10/15 mins time I'd allowed and called the agency in a panic. Arrived 10 mins late, which is obviously a big no no, and put me in a complete spin...
Walked through the whole office, sat in a room where they wanted to record the interview...
Struggled through the questions feeling rushed, as they kept bringing up how little time they had due to me being late..
I'd prepared a presentation (staying up late to get it done as well as the agency had only given me 3 days notice, and I was already working)... they asked me just to summarise it real quick...As you've guessed...my lateness meant I didn't have time to deliver my 10 min presentation properly....
I still wonder why I bothered staying and didn't have the confidence to turn around, apologise for wasting their time, and left early to have time to pick up a consolitatry Costa before work...as I pretty much knew I'd messed it up the moment I walked in.
Plus the mini parade through the office, I would have HATED working in that environment.
