How CONCRET.IO masters Salesforce using Trailhead

This video gives an overview of how concret.io is using Trailhead to learn Salesforce, and train new hires. We use teamwork.com to create task templates, which contain 20 days training program for new hires. Every day we have a bunch of trailhead modules, and trailhead projects/exercises. A senior developer or architect gives an overview of these trails to a new hire, they can then complete the trails on their own.
