And this specifically introduces transactional boundaries, which can introduce a lot of complexity.
Especially in games where the domains (thus boundaries) may change a lot during development as the game design is being figured out.
My experience is that in well-running teams, devs are usually pretty aligned what these numbers mean. A difference in proposed points for some task does then usually mean there's a discrepancy in knowledge about it.
As for its usefulness: You of course don't have to necessarily poker to get these discrepancies, but it's a pretty effective way of going about it, I'd say.
Hey. Also Dutch. Most of the things being asked are pretty normal to me (but it's more than I would expect a company to ask for...). I only find the IBAN weird to ask. Did you ask the company why they want your IBAN already? If it's a valid company, I'm pretty sure they're able to answer you.

I spent more time reading the threads than I should have, it's strangely addicting. I now feel naive for thinking that the people working at the big tech companies have a certain base level of "all-round" skills. In no way I expected so much cynicism, narcism and lack of empathy! Isn't this showing up in interviews? Or should it just be seen as online trolling and venting?
