hi /pr/

I'm a CS grad, bachelors from a top university. I did decently well in school though I definitely struggled in some classes like Operating Systems.

I got a job at a decent tier 2 company as a software developer. I'm good at my job and people recognize that. This was like 4 years ago.

I've been looking to switch to a FAANG since TC is nuts. I have multiple friends who work at FAANG's and they've told me about the interview process.

It's gotten much tougher in the last 10 years. It used to be rather simple linked list/basic data structure questions, but now due to how competitive and saturated the market is, they've raised the bar high.

You're guaranteed to run into a graph and/or matrice question. Problem is I can't seem to wrap my fucking head around them. I get you're supposed to understand them instead of memorizing them but... how?

Any advice? Also, is it worth learning Union Sort when DFS seems to suffice for most leetcode questions? I know both are good to have but my brain has limited bandwidth.
