If I were hiring someone to figure out which buttons to turn from red to blue, I would at least try to find people curious and serious about the task. I wouldn't just accept that its monkey work, throw some money at it and hope for the best.
I agree that the learning part is interesting but at google I suspect those are two different jobs.
That's why Google ends up with 25 shades of blue because each button is "scientifically interestingly A/B tested to death": "When you desgined 5 screens in Figma, but couldn't be bothered to chose the better buttons, fought with managers and requested an A/B/C/D/E test" https://twitter.com/nikitonsky/status/1555686876274630656 and https://twitter.com/nikitonsky/status/1557755746686754818
Every time i see businesses taliing about passion, they are aiming to underpay and exploit employees.
Gaming industry has the most passion, very skilled people and the worst working conditions in the entire IT.
Capitalism for me but not for thee
The place I work is actually nice, but since that realisation, I managed to get an offer from a different place, to make my current company to counter with a massive salary increase.
I know and also share the salary numbers with most of my closer friends in the company, so I know how good I'm doing. If they stop giving me the fair regular salary increases, then I'll leave without any regrets.
Lesson for me that blind loyalty - even in nice places - will give you nothing but frustration and exploitation.
It's also a false dichotomy: I am both passionate about my work and could do it for free (which I do with F/OSS contributions), but I also care about my compensation.
