> Regardless of personalities, the most important factor is profit. Everything else is secondary. It is not as flashy or famous as big tech companies, but this profit is paid in bonuses that far exceed the highest salaries for tech workers.
Depends a bit on what part of fintech you are working on.
There's lots of rank-and-file employees whose good salaries actually mostly depends on competition from tech companies. With a low-risk lifestyle mostly comparable to said tech companies.
To get the crazy bonuses, you need to move closer to the traders and some of the quants (or get very lucky). But generally those people work a lot harder and longer.
I've worked in tech companies (like Google and Facebook) and in those low-risk fintech roles (at eg Bloomberg and Goldman).
It seems that the finance industry as a whole seems to be moving away from the heroic model with enormous bonuses to the tech company model with good salaries.
The latter is cheaper and more predictable, and it fits the organisations as more and more work becomes automated.
(That observation is about companies like eg Goldman and only meant to capture an average. They still have plenty of individuals pulling heroics; and there are still plenty of hedge funds and similar on the old model.)
As another example, take high frequency trading market makers. They generally don't have any human traders at all, because humans would be way too slow. So their very nature forces them to become closer to tech companies in organisation.
