I will say that different industries have different formalities (generally speaking). But that just means you have to interview with smarter attire in FinTech vs interviewing for a job in gambling.
As a hiring manager, I can say that companies will recruit for as little as they think candidates will accept. Fintech gets a bit of a pass on this one but only because they rake in so much money that they can generally afford to attract higher salaries. But it does also mean that gaming can get away with paying people peanuts in comparison and that is literally due to supply and demand.
In places where the C-suite have set unrealistic thresholds on tech salaries, I’ve had to get creative to attract candidates. And that often meant contributing back to open source and basically using that as advertising.
Anyway, this is already a verbose reply but the crux of it is:
1. you shouldn’t underestimate the power of supply and demand in the work space
2. The profitability of a sector also plays heavily into the equation
3. You don’t need to be posh to get a job in FinTech.
