Is Leetcode good just for entry level roles or is it good for more senior roles as well? Suggestions for senior roles?

Oooh..."senior"

Leetcode is a must for most companies you would probably apply to. But to differentiate you from others, level wise, it depends on your system design and behavioral interview results. Good luck.

Two views: 1. 8 YoE should have had many years of LC practice 2. Forgetting algorithms and data structures after graduation Overall, they roughly cancel out so it's about the same regardless

you'll need LC if you have only 8 yoe.

its a cancer so its every role. don't remember where I read it but someone that interviewed for a CTO position got asked a LC question in js it was jokes
