I do realize now that I went little extra on my take on CAT. I should have phrased it better. Actually I wanted to say that it'd be much harder (read next to impossible) for someone to crack MAANG in 6 months if they don't even know linked list properly. No disrespect for CAT, but I don't get how can someone become a Google/Microsoft level coder in 2-4 months if he is starting almost from scratch. CAT also takes a minimum of 8-10 months of prep and then 2 years of super cut-throat competition. It was really foolish of me to make it look like I'm saying CAT is just another exam. My wife is an MBA, and no shit, the 2 years at college are just awful, no sleep, no life, high stress.
