[BB-6341] newcomer feedback - Navin Karkera

Overall the course was good. Detailed explanation of most the things can be found in handbook, course or private docs.

The only improvement other than the ones already reported that I can think of would be to include more visuals to make it more engaging. Although I am not sure on how to do that myself.

The sales talk by Doug was especially interesting. Looking forward for more such talks.
