I applied online. The process took 2 weeks. I interviewed at ZS Associates (Philadelphia, PA) in Mar 2011
Interview
The first round interview consisted of a 30 min case study and a 30 min behavioral interview. They asked relatively standard questions. The case study involved profit maximization as well as being able to interpret graphs and charts. The case study involves some solving of numbers which was a bit difficult seeing that you are unable to use a calculator.
Interview questions [1]
Question 1
"When have you ever began a project without a specific outcome in mind.
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
