Zillow Marketing Manager, SEM interview questions

Phone screen with recruiter. In-office visit to take 30-minute Excel test and speak with SEM director briefly. Interview was on a Friday, received automated rejection notice Monday. I was disappointed to not get a follow-up interview. I have no idea what I did wrong. In any event, it's Zillow's loss because I would have knocked it out of the park for them. The recruiter was really nice.
