My hardest interview was at Roblox (passing Google and Apple). After passing the normal coding + system design questions, they throw you at leadership who ask you a random analytical question. I struggled with knowing what sort of depth to go into, and asking clarifying questions did not help.
~$340k for my apps. This is why I thought they would never make a change, because people would be upset without retroactivity (which they would never do).
This is exciting for small devs, even if not life-changing.
I made 42k in the last 365 days after Apple's 30% cut (or 60k in sales). That means I will get to keep an extra 9k next year, assuming revenue stays flat (it mostly has).
I would bet that if one is unsavvy about it one gets paid out about as quickly as they pay vendors (which can be glacial) but that a demand letter to the general counsel with a judgement attached results in a check getting cut no later than the business day after the day the letter is opened.
