There was a brief phone call with one of the senior editors. Media diet was discussed; current trending topics; professional goals; how to write a good headline; etc. Then an editorial test to write two articles within an hour while making sure it was accurate and abiding primary sourcing. This was followed by a technical interview in the newsroom where you had to identify ~50 prominent figures to test your political and cultural knowledge. This was also in addition to a cultural interview to see if you were fit for HuffPost. Then a final interview with Arianna Huffington herself.
