I interviewed at the San Francisco location. Very Straight forward and the interviewers really tried to get a sense of fit within their company. Everyone that interviewed me was very nice and passionate about their job and were honest about what they learned from working at WTW as versus other firms. 1st round was an on campus interview and the 2nd round was a super day interview at the office followed by a lunch.

one 30 minute on-campus interview then big day with 4 different interviewers for 30 minutes each. Super friendly interviewers, and all really easy behavioral questions, mainly based off of work experience on my resume. Also asked about how I've used Excel in different jobs
