The key differences for us are we are very focused on existing experienced engineers that want to learn new technologies in a hands-on accelerated way amongst peers. We offer our courses in the evenings around a job schedule and the courses are free of charge. Our business depends on helping those interested find jobs they love.

"Highest quality" is a complicated thing to define but suffice to say it is in part about creating ultra high quality. We provide detailed videos, extensive wikis, hands-on projects, open-source and closed-source libraries, and extensive mentorship. We also have a process for selection of our candidates that involves a phone screen and a short in-person interview to assess background and commitment to the program.
