It was Summersault Challenge, for civil engineers,unstop registrations, followed by Aptitude test and Case study and finally Interview, those peps only shortlisted 80% women and 20% men. and for interviews all women :) took 6 of them. Similar for summer inters, they took men from iits. If they shortlist you and u are not from iit nit or a gud clg then they just want to maintain the gender ratio. Fair enough.
