Information Regarding Amazon Alexa Org?

I have a verbal offer for a Sr. Program Manager position from Amazon as a result of an invitation only hiring event. No compensation details yet, but phone calls will be set up with dev managers from three groups in the Alexa Org, and it seems like I get to pick. The three groups are Alexa Smart Home, Alexa Skills, and Alexa Devices. I would be interested in opinions and insights into these groups. Thanks!
