Zappos employees have Amazon Badges?

Aloha Fellow Blinders, I recently had my final onsite interview with Zappos and honestly, I really liked the team. One thing I noticed was that most, NOT all, of my inteviewers had two different badges: One was Zapponian and the other was Amazonian. I am still waiting to hear back on whether I will get the PM positon or not and the HR didnt even mention the base pay as of yet. She just said that Vegas is 65 percent less expensive to live in than San Fransisco and the compensation will be based on the same. Plus no state tax in vegas.. A few questions 1) How much does a zapponian PM in Las Vegas make? Less than Amazon ? 2) Are zapponians eligible for amazon Stock options? 3) What do Amazonians think of Zapponians? 4) How relatively easy/hard is it to transfer to Amazon from Zappos? About myself: Ex-PM at a niche retail in India (3 years) Ex-Senior PM at Amazon (just did an internship so i am not sure if i should call myself an ex-Amazonian but what the heck)
