This is absolutely a huge problem and a giant topic. I don't have a ton of time to proactively help you but feel free to add me to a thread or discord as I do have a lot of behind the scenes perspective.
In case you don't know me, I do not run a bootcamp but I do work on a mentorship platform for experienced engineers and as a result work with a ton of bootcamp grads a few years down the line and hear about a lot of programs.
I don't know much about Le Wagon specifically though only worked with a couple of people that went there.

What’s the mentorship platform?

It's Formation ([formation.dev](https://formation.dev)). It's for people with 1 year or more SWE work experience (and typically MUCH more) but a lot of people we work with are doing their 2nd, 3rd, 4th job transition. We're not a school or education program or teach anything, rather it's practice and mentorship experience to get interview ready at top tier companies.
