I interviewed for Barclays once, in their offices near Tower Hill. I walked around and around, and could NOT find the entrance to their building. I managed to call as I was going to be late, and the interviewer kindly talked me in and reassured me that no one could find it as the entrance was hidden.
By now I was flustered, sweaty, and could feel a migraine building. It all started well enough, but then my vision went peculiar and the throbbing of a true migraine started. My answers were getting shorter and shorter as the nausea got worse and worse, and I must've gone white because she brought me some water and moved the bin a bit closer. I didn't vomit but she wrapped up the interview pretty quickly and I didn't get the job, God knows what bollocks I came out with.
That wasn't the worst of it though - I actually had another interview straight afterwards, over on Oxford Street. I was an hour late so the agency called ahead to make sure they'd wait for me, then I had to work my way to the next one by tube, trying not to puke down myself, and it had also started raining so I was a frizzy mess to boot.
I arrived at reception and...they'd all gone home, they didn't wait for me after all.
It was a shitty crappy day, I was very relieved to get home where I crawled into bed!
Oh - I also car crashed an interview when I was not at my best, mental health wise. No one in their right mind would've employed me, I was unhinged and came out with some utter shite...
