It is difficult to pinpoint what exactly gives a giant corporation like Google its famous startup culture. Perhaps it's the independence people enjoy, the absence of red tape or the freedom to disagree.

Or it could be that the search giant has managed to pick the right lot of people - those who can come up with next big idea, or better still, help a colleague come up with it. And this becomes glaringly obvious to those for whom Google was not their first employer. Ramesh Ravishankar had worked with other firms before he joined Google Hyderabad and realised that this was a wholly different workplace.
