Before I was a lead research engineer at CMU, I only rarely showed up on search results for FAANG companies. After a few months of being there, I started appearing rather frequently, and their recruiters would even argue with me that I should interview with them. A Facebook recruiter once told me they targeted me specifically because and I quote, "we know smart people are there". My favorite line of BS from them was when an Instagram recruiter tried to tell me, "everyone is our kind of candidate" LOL!
Being a lead research engineer isn't quite the same as being one of the PhD students. Although I did get quite a few people there who insisted I would be great for FAANG, it remains impossible to get in. Meh. I refuse to pay for leetcode premium and effectively cheese my way in.
