Hey I just want to add, in addition to your advice here, there are other important aspects to interviewing beyond performance on Leetcode questions. In other words, it's sometimes necessary, but not sufficient. Most senior jobs require system design interviews, conversations about leadership, and more.
I think "grinding" on Leetcode also entails learning and practicing a lot of irrelevant topics for many jobs, but there are newer resources out there that help you focus on what you need to know for specific roles. I don't like to plug my own company, but Exponent[1] is designed to help with this more 'well-rounded' interview prep for different types of engineering paths, and we also have a mock interview feature that helps you iron out your communication skills with other candidates.
I would like to try exponent, but the only free "lessons" I see are the intros to each section. I want to see a real, representative sample of the content I'd get before I'm willing to open my wallet.
