They explain the concepts and then point you to additional resources for learning the material (like youtub videos and specific codewars problems) Very helpful.

This repo covers at a high level things ranging from *Career Tips* to *Data Structures*, *Security*, *Architecture* and *Algorithms*. It's a lot but can be helpful to overview concepts and find new things to learn

- **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.

- :octocat: **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.
