Is Twitch Streamer / SWE @Primeagen just a gifted engineer? He just easily went through easy, medium & hard leetcodes and doesn't even practice them?

I see so many engineers here saying that they have years of industry experience but when they are on the job search, they post here about having such a difficult time doing leetcode problems.

Yet the Primeagen easily just solved easy, medium and hard problems (last problem got time limit exceeded but it was still correct). I didn't even think that these problems would be things an engineer would encounter day to day at work, so how did he do these so easily?

He struggles a bit with the first question, but he flies through the more difficult ones. This kinda makes me feel useless just practicing so many leetcode problems every day. Maybe I'm just bad lmao
