If this true, why doesn't FAANG have the same problems? I noticed that your post did not discuss any of the negatives about your company or its offers. When I have struggled in the past to hire, it is always because my company or its offers were pathetic. Pretty simple. If your company or offers are weak, then your candidate pipeline will (likely) be weak.
Plenty of candidates, just not many that are good.
We're fintech, so it's boring. We don't do AI and we don't move fast and break things because that would cost us more than we'd make. We just move faster than the competition. Similar companies would be Stripe/SoFi.
