Oof. Imposter syndrome is real and it's debilitating. If a person does their job to the best of their ability and stops giving a fuck about what others might think, it becomes easier to overcome.

OP needs to realize that engineering is not about memorizing algorithms or being in the top 5%. It's about doing whatever work you are paid to do efficiently and quickly. Quite honestly, most "engineers" I know don't even do that much.

Monday through Friday/8-5, engineering is about solving stupid problems and getting a paid for it. That's it. (Maybe you have to go to meetings too.)

Some engineers can memorize formulas and rattle off 200 ways to do a thing. Some engineers are constantly in some kind of dick-swinging contest with their peers. Some are constantly chasing the "new shiny" and won't shut the fuck up about it. The most annoying ones blast out "helpful code segments" on LinkedIn to make themselves look smarter.

Fuck all that noise. It's annoying, a distraction and it'll cause a person to get burned out of the field super quick.

Sorry if that was a bit of a rant, but I have seen too many bright eyed Jr. engineers get crushed by the bullshit that can go on.
