My company (Moloco, Inc.) opened a new Youtube channel - MolocoLife. We had one (Moloco channel) before, but it was mainly for our clients (advertisers). This new one was more about the company culture and people - mainly for employees and new hire candidates.
Even though I worked in this company for more than five years, we've grown up so fast, and there are so many things and people I don't know of. Both channels are great sources for learning many aspects of my company.
