> Exponential inner loops for big searches, huge recursive calls. Those things show up in code written by experienced coders IRL.

The thing is, those things are easily fixable after the fact. A bad architecture is not, and without practical experience designing systems in the real world, you don't have those instincts to guide you towards the correct choices because you haven't made any mistakes to learn from.

And thanks to modern CPU design, they are often actually faster than more complicated data structures.

I know in interviews they are looking for the solution that is the most efficient by big O standards so that’s what I use

But big O is often just not a reflection of actual performance on modern computers
