Not saying you are wrong, but when does management even know exactly which specific X caused how much increase in revenue, let alone a software developer.
For example: you coded and launched a new feature, and that feature brought in 20% more users over the following year. Sure, there were probably other factors that helped, but when you can point at specific things and back them up with metrics, it's 100% better than just listing a bunch of skills and jobs.
In the UK market folks aren't particularly receptive to that sort of thing.
- Some think I'm no longer technical enough because I've done managerial stuff, despite recent work being hands on.
- Some think I'm not managerial enough because I still do technical stuff.
- Some think I've somehow failed because the specific role was only ~20 months ( it was actually equity shenanigans )
- Some think I'm too senior and won't stick around ( despite the role being top of the market pay wise )
Mostly, I don't really know, because when going through the front door, they typically don't respond, and in actual fact the only leads I get are the ones that contact me.
But I think our specific culture focuses on reasons to say no, rather than reasons to say yes, and the current market only helps compound this, even if the outcome is worse.
Of course, I might just be shit, but they also likely don't know that by not speaking with me. :)
Even if I did, it was probably someone else's idea, someone else decided it would be worth adding to the product, someone else made a UX and UI design, I wrote the code, someone else tested it, maybe there were some iterations of those. It's all team work.
Someone claiming such a increase as their personal achievement is spouting BS and would not get an invitation here.
SMH.
None of the companies I worked at disclosed to the engineers what features led to what results. So I made shit up and nobody called me out on it.
