GreatFrontEnd has been instrumental to all my interview prep - I've relied extensively on it to prepare for and ace interviews at big tech companies and startups alike. I remember getting the lifetime plan as soon as it came out in 2023 and have immensely benefitted from it - it is one of the best ROIs I've ever had. As a mid level engineer, I particularly benefitted from the behavioral guidebook as behavioral interviews are core to leveling decisions. I couldn't have done it without GreatFrontEnd!
