There was one phone interview (they asked how to remove duplicates from an array) followed by onsite interview in Chicago. During the onsite, I was put up in a nice hotel and had a full day of interviews. They have coding station where you do some fairly basic Java coding (code a few functions to implement using hashsets) , an algs station (find anagrams of words, a byte suffix problem), and an HR station (go over your resume piece by piece). It was a fairly good experience overall.
