I recently switched to a different part of my organisation a slightly more senior role. This was because there wasn't likely to be an opportunity for promotion in that team so felt it was best to move on.
I knew very quickly it probably wasn't the best move for me and I really missed the previous work.
Within a week my previous manager contacted me to tell me they had been able to agree a new post within my old team which would be ideal for me.
My old manager plus lots of other seniors really encouraged me to go for it and said I would be a shoe in after all my hard work etc
I really prepped for the interview workimh hours every evening sorting presentation practising answers etc
I didn't get it. Noone did they went out for advert again. I thought I did OK at interview but it obviously wasn't good enough.
I'm still absolutely gutted I would have loved that job and I've worked so hard. I could still cry 2 weeks later feels like I missed my big shot. My confidence is at 0 so won't be attempting it again
