Interview was easy and fine , no hard questions as such , just basic conceptual questionnaire. They mainly focussed on tech skills and niche approach. Some questions were direct like How would you seggregate non returning cutomers from overall customer group available ? Overall they would check your suitability in your organinsation as to how would you fit in . Brush up the basics and that should be it. Go through your basics and books and lectures and that should turn out to be more than helpful as usual should reaeearch up a bit about the company you are applying for and that should do the work for you.
