Survivor bias alert: These people have all passed the interviews.

I wonder if this is an intended side-effect, namely also filtering out people who would have passed if only they did rote memorization instead of actually mastering the CS fundamentals.

I probably spent a month and a half studying most days for it (including reading my old data structures and algorithms books). It's the first time in my career I actually tried to prepare for a LC-style interview, and tbh it really wasn't bad. I also had a good experience and am still in the position, so YMMV.

How did you get so good? Would love any tips
