Thank you for creating the incredible resource, GreatFrontend. It was crucial in helping me prepare for interviews and secure job offers. Having focused on strategy and management recently as a Staff UI/UX Engineer at Twitter and Tech Lead Manager at X, I realized I needed to refresh my technical skills. In my opinion, GreatFrontend offers far superior content for frontend interview preparation compared to alternatives like Leetcode or HackerRank or CodeSignal. I truly appreciate the hard work your team has put into this resource. It's one of the few offerings on the internet that justifies the subscription cost, providing tremendous returns on investment.
