Have you tried figuring out a recommended course pace? Obviously if you have like 4 weeks before you start interviewing you just have to grind and practice a lot, but what if you currently have a full time job and you're thinking to target some of the FAANGS 6 months from now? Would you take a breadth first approach and go through all the patterns then come back through the practice problems? Would you recommend a 1 at a time approach and really try to dig into each pattern?
