KCO Corp (umbrella term for Gen Corp, M&A, PE) Mumbai underwent restructuring last year and is now 3-4 partners with a shared pool of resources. Pro/ con - you're with particular partners who may have a type of client/ work they get and there may be little chance of diversification/ working with other corp teams. KCO Delhi has a bigger pool with no official verticals. Partners usually have a certain set of resources across levels that they staff on their matters but there is comparatively more scope of working with others. Cons - it may be hard at certain times to balance between deliverables of different transactions with different partners. Its a skill that takes effort and time to acquire.
Delhi and Mumbai please. Seen some posts where people say it is not structured well but no further information.
