Not able to down level

I am a fourth year UG, I used to do mock interviews with a Amazon SDE(luckily found him on reddit) and we did it for quite a long time but then he got selected in Google and has stopped it now for some time

So I started looking out for someone till then and had a meet with 3-4 people but I realised their coding standards are much lower like bad variable naming ( and these were experiencd people with 2-3 YEO in pbc), no proper explanation and walkthrough, no clarifications, also we used to solve mostly hards but the people I met wanted to discuss around mediums only

Is it now impossible to find somebody good from interview perspective
