I applied online and was invited to a first-round interview, 1/2 behavioral 1/2 case. The case was pretty easy and about CPG products. Soon after I was invited to a final round in person in Chicago, with a full day of interviews, intermixed with another case and a math test. Everyone was nice but the math test was pretty hard and 95% of the staff was much older than a fresh college grad. I heard back about a week later via email that I did not get the job, with no feedback, which was frustrating. People were nice but the office was in the back corner of a shared floor and the firm didn't really excite me.
