I applied through college or university. The process took 1 day. I interviewed at ZS Associates (Chicago, IL) in Nov 2011
Interview
Initial on-campus interview which consisted of two parts, a personality interview and a typical case. Second round interview spanned a few hours at the Evanston branch and consisted of a couple case interview, a presentation given by a co-worker, another personality portion, and lunch with an associate.
Interview questions [1]
Question 1
If you were to set up a hardware store around town, how would you go about doing so?
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
