I just started leetcoding. Will I still have enough time (with around 4 hours per day) to prepare for FAANG internship interviews within 1.5-2 months from now?

  A pattern-based approach for learning technical interview questions

When I started grinding I had already taken a DS course so I was at least aware of hashmaps, arrays, trees, etc. but even leetcode easies we’re still a struggle and the ones I could do I wasn’t solving them optimally. Having that basic knowledge though allowed me to start struggling through the book I mentioned. EPI is harder than CTCI but it’s language specific and I already knew I was going to use python. I completely skipped bit manipulation and tries but I ended up getting a trie question in one of my interviews and that was by far the hardest question I’ve ever gotten, probably because i skipped tries altogether lol. I haven’t tried grokking. I started doing EPI by hand so that I was forced to think through solutions before writing them but if you feel like that’s unnecessary for you just type it but it def helped me since in interviews you have to discuss before coding. The DP section of epi was really hard so I didn’t complete it. From there I just started struggling through LC. After epi I started with easies but i didn’t stay there for long since epi is mostly mediums and some hards anyways. The biggest thing is to learn from every problem, even the ones you don’t finish. Truly take the time to understand a solution even if that means 45+ minutes of digging into it. The same patterns come up again and again so you’ll have to dig into them eventually. Identifying the patterns from the way questions are phrased come from quantity I feel like so doing a lot of LC problems is the way to go. My pattern recognition was on point after about 100 problems in total maybe. For LC i did 95% of all easies and mediums in [this]. Earlier I said I skipped DP in epi but def do dp leetcode problems. You don’t have to master it but def become familiar. If by the end of everything you’re able to knock out 70+ medium level questions then you should probably be good for internship interviews. Hope this helps and also if you take the blind 75 route NeetCode on YouTube has done all of them I think and he’s really good with explaining the problems. Take the time to understand each data structure individually before even attempting problems. I think EPI does a good job of that or you can just hop on YouTube. Good luck Glum Choice, I have faith that you will prevail 🏅
