ZS Associates interview questions

Applied for a job on Sept 17th for various locations and was chosen for the SF office interviews. Was approached by an HR person, who was very professional and friendly. Agreeing that I have the right background, she scheduled the first round of interviews for the first week of October. Following the schedule, I spent 30 min with a partner discussing team work and my approach to work related situations - behavioral interview. The business case interview was scheduled separately, in two weeks time, and I spent another 30 min solving an unstructured business case, estimating the patients pool for Myeloblastoma in the US. This is a typical market sizing exercise - pretty basic if you have experience in pharma/biotech forecasting/modeling. I have not had any feedback for weeks and decided that they will not pursue with my candidacy when, in a month, I received an invitation for the second, final rounds of interview, for which I gave my consent. Because I was interviewing for the San Mateo office, I assumed that they would fly me to the area but they decided to send me to NJ, although my location is Boston. I have been in contact with 3 admin assistants, trying to work out the details. Finally I received the agenda for the meeting but not in NJ, Princeton but in MA, Boston. This interview was scheduled for December, just right before Thanksgiving. It suppose to be one business case interview, one panel interview, and the behavioral interview with the partner. When I arrived to the office, they notified me that I am 45 min early. I showed my itineraries and they apologized, claiming that the admin in the NJ office forgot to send me the right time. The business case was pretty basic, unstructured; I had lots of fun, conversing with the Associate from the San Mateo office. The case was a pharma case, sizing the post - resectable breast cancer patients segment eligible for the reconstructive surgery. The second part was a panel interview estimating strategy for increasing the bottom line and assuring the steady growth of a wine pub chain in the UK. It was fun as well, lots of data but pretty basic and straight forward. The third part, the behavioral interview was canceled, and rescheduled for the following day. The partner from the NJ office called me and we discussed various difficult situation that consultants encounter with the clients. All in all, I had a good feeling about my performance. It has been almost 2 months and I have not heard anything from them. The whole process is taking almost 5 months and I am not sure if they ever would contact me back.

Was reached through LinkedIn by recruiter who invited me to a phone screen. Did phone screen and was invited to phone interview with consultant and manager.. Two interviews of 30 min. each consisting of Case Question and a Behavioral one.
