I applied online. The process took 3 weeks. I interviewed at ZS Associates (Philadelphia, PA) in Oct 2011
Interview
The first round was a phone interview of app. 1 hour, where we discussed the usual background info and analyzed a case of app. 30 min. Mostly about Sales Territory and sales force optimization. Very friendly and helpful during the case, dialogue situation.
The final round consisted of a total of 5 interactions, one background/personality fit interview with a Principal, one guided case interview with a Senior Consultant, a product introduction (Javaline, ZS' territory software) with a Business Associate, a lunch with a Business Associate as a direct dialogue and a final case study of 40 min. with a Manager.
All interaction was very friendly and the atmosphere was pleasant.
Interview questions [1]
Question 1
Why do you think it can be problematic to allocate sales rep territories across state boarders?
Good interview started from basics went in deep about sql python and projects as well. Did cross questioning on projects and then ended with a some behavioural questions. Overall a very nice experience.
they take an online test of verbal, data interpretation, aptitude, etc. They also ask a question which you have to reply through a video, where they will give you a random topic, you have to record a video speaking about the topic for 60 to 90 seconds.
The interview process is a bit difficult to crack. Go through your resume and be ready to answer whatever they ask about it.
Practice guesstimates and puzzles thoroughly. Be consistent with your logic in solving problems
