They explain the concepts and then point you to additional resources for learning the material (like youtub videos and specific codewars problems) Very helpful.
Coderbyte - https://coderbyte.com/challenges/?a=true - Lots of programming challenges, access 10 for free otherwise $30 per month

This repo covers at a high level things ranging from Career Tips to Data Structures, Security, Architecture and Algorithms.

Finding companies to apply to

https://whoishiring.io/ - Most impressive job site aggregator I've ever seen in my life. Scrapes all the boards and has a map of where every company is located.
https://huntr.co/ - Tool for keeping your applications and search organized on a Trello-style board. they also have a chrome extension for quickly adding jobs from various sources.
https://breezy.hr - I used this one as a recruiter. It is actually built for HR departments but has a chrome extension and can be helpful for adding people and specific individuals you're reaching out to. This way you remember to follow up and can find like-minded people. One catch is that you need a custom email address like @your-domain.com. Signing up with your gmail account won't work.
https://betalist.com/jobs/collections - companies and jobs grouped by category like female led startup or decentralize all the things for blockchain related jobs.
https://github.com/connor11528/sf-companies - shameless plug here. I've got another repo going with companies located in downtown San Francisco. The data is available as a CSV file and includes company addresses.
