A place for everything about math

I did so many of these. Yes it's a excellent resource

Project Euler is the lifehack for job interview prep.

Find problems that are appropriate for your skill level, write out answers on paper or on a whiteboard, then once you're happy with them, put them into the computer and fix them up until they run. Keep doing that until you feel well-practiced with your ability to put code together without having an editor and think quickly about new problems you've never seen before. (For me it took a few days of practice.) Congratulations, you're now the guy or gal who can show up and eat the interview problems alive and look comfortable and confident doing it.

@Pudutr0n When I was a PhD student and procrastinating on writing my thesis I did too many Project Euler problems.

I did quite a lot of them maybe 10 years ago. Are they still being updated?

Is it pounced “oil-er” or “yoo-ler”?
