There is no specific way to crack a consulting interview but one can always go prepared. One of my friend was with avalon consulting based out of mumbai. His interview was based on his cv, basic industry knowledge, various ways of analysding strategies like swot, mckinsey matrix, evaluation technicques etc. Also, aptitude tests r generally conducted similar to CAT.. Quant, DI and english. The consulting firms also prefer a strong and consistent education perfoemance. In short, keep your basic concepts crisp and clear
Consulting cos are quite strict while selecting employees. Most important thing is the knowledge and analytical skills that they posses. Expertise in a certain sector is also equally important. Also, if from a reputed B-School, then also it matters!
