Question 1
How are you suitable for the company? puzzle type questions
I applied through college or university. The process took 2 days. I interviewed at ZS Associates (Pune) in Sep 2013
Interview
Written exam followed by one ground discussion and 3 rounds of interview - one case interview, one technical and one HR interview. The entire process took 2 weeks. It was a campus offer. The interviews were tough, specially the case interview if you have not dealt with data or cases before. Just keep a keen eye on any outliers and make observations about the data provided.
Also, prepare guess estimate and basic HR questions thoroughly. They might also ask puzzles in the fit interview. Staying confident and having good communication skills might compensate for any technical downsides.
