I really despise solving competitive programming problems.

I truly believe it's okay to struggle with them and that people have different abilities. But these kind of problems are an easy way to make you hate yourself and think of yourself less.

I can't solve this problem --> I'm not a good programmer --> I'm not smart enough --> I'm not good enough like my peers who work at FA*G companies, ...

I know these interview problems are a filter and that recruiting is hard and the demand is always high and that they are nothing like the real work but, the reality is, you need to prepare if you want to get into one of the big companies with better perks and maybe better projects.
