It didn't take long for cities across North America to throw their hat in the ring when Amazon announced it had initiated a search for a city in which to build a second headquarters.    In seeking proposals, Amazon laid out some very definite criteria, including population requirements (one million or more). CNBC examined the criteria and suggested that five cities are worthy of a close look by Amazon: New York, Atlanta, Chicago, San Francisco and Boston.   

The search is on for Amazon.    The e-commerce giant is currently evaluating where it will open its second company headquarters in North America. The new office, referred to as "HQ2," will be a complete headquarters — not a satellite office. It also could have a similar layout to Amazon's Seattle campus, which employs 40,000 people, and encompasses 8.1 million sq. ft. with 33 buildings, including 24 restaurants.
