So in my previous job, I basically fully vin charge of this type of tasks and would bring in business in the millions. Some of my projects included big brands such as Ford, Amazon, Adidas, Totale, etc... I really enjoyed it too, and was offered to do it as my FT day job at some point but the starts didn't align.
Anyway, in my new job, a similar project came in that was biggest than any other contract we could have. I volunteered to do it as a passion project because I had the experience etc... They were a bit pessimistic we could win, but I knew it was worth the shot.
Fast forward to at some point last week they gave me a "nanny" that has been bossing me around and didn't give any credit for my previous experience. I would have done it fairly differently. What really annoys me is that nobody has the same experience as me (in terms of size of contract).
I'll still do it, but obviously not with the same gusto and feel very demoralised.
