ARLINGTON — Despite the heat and lengthy lines, some 5,000 prospective Amazon employees descended on Arlington, Virginia, on Tuesday to participate in Amazon Career Day, the e-commerce giant's largest recruitment effort to date. 

The event — which was held in six major US cities: Boston, Chicago, Dallas, Nashville, Seattle, and Arlington — is part of Amazon's push to fill 30,000 open jobs across corporate offices, fulfillment centers, and stores. It event builds upon smaller-scale employment events such as Amazon Jobs Day, a 2017 career fair held at a company warehouse in New Jersey. 

We visited Amazon Career Day in Arlington, which is also the new location of Amazon's forthcoming second headquarters, or HQ2. Despite the incredibly crowded venue, there was an air of optimism and hopefulness among the diverse array of attendees, spanning all walks of life.

Though Amazon did not take applications, conduct interviews, or make official offers at the event, it featured informational booths, panel discussions, and job development tools. Several attendees came with resumes and briefcases at the ready for on-site resume reviewing and interview tips, which was by far the most sought-after service in Arlington. 

Ardine Williams, vice president of workforce development at Amazon, told Business Insider the event was largely a response to feedback from attendees of previous career development events who indicated they wanted more than just a "singular view" of the company. 

"This is a chance for people to really get to the next level and explore and understand [the company]," she said."It gives them the chance to get a view of the broad range of opportunities that exist at Amazon."
