well , it was a walk-in for all the graduates who are having ccna cert (mandatory) and ccna (optional) , even if you don't have the later cert ,at least you should have the basic idea of what it is all about. the first round was an assessment test which was the same like appearing for the cert exam, for clearing the first round you better know your stuff , second round was technical round with the tech lead, followed by the agm and finally the hr, everyone was so helpful and intellectual , they are great people , that is the reason why this company is reaching new heights, i will sum it up as the best interview experience ever, if you got selected then everyone will help you at every point , they will be in touch , one of the thing i liked the most.
