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.

To the point and purely technical based. With requirement for soft skills like communication and coordination. Experienced candidates are asked further detailed questions related to their past field. I had an hour long interview process discussing my education and internship details.
