I always find it strange the way people talk about the importance of Leetcode on here. I've been in the industry 7.5 years and I've never used or been asked to use leetcode or really any site like it. I've gotten the CS questions in interviews and some coding problems that are perhaps leetcode-like; but the latter are usually not super intense, either in difficulty or in grading harshness. My solutions never had to be perfect, they just wanted to watch me problem-solve. And most of the companies I've worked for would be called "trendy"; we're not talking about stodgy enterprise-type orgs. I don't get it. Is it because I'm not pursuing FAANG? Is it because I'm in Austin instead of SF?
