Wayfair Talent Acquisition & Strategy Associate interview questions

Wayfair came to my school so I attended the information session and then applied online. I had a first-round video case interview. I was offered a final in-person interview. The original date of my interview was pushed back a month and then happened to fall during final exams. I rescheduled all of my exams in order to fly to Boston. A week before my interview a person that I had not talked to during the process called to tell me that the position is now filled/changed/cancelled. This was my way of getting home from school so I had to find other plans at the last minute. The way they went about this cancelation was very unprofessional and offered little to no help afterwards.
