Your second paragraph tells you who you’re trying to find in your third paragraph: FAANG. Hiring 500 engineers and bragging about it something you can do when you’re just interested in shareholder value not customer experience.
I wouldn’t hire the guy in the article because I haven’t seen strong candidates come from FAANG and I’ve been very happy to lose the people I did to FAANG because they weren’t good engineers, they just knew how to leetcode and tunnel vision trivia.
