It was walk in interview, they make people to wait for longer hours and first to stand outside and then they check resume and govt ID with passport size photo after that they check our bags and allow you inside and provide interview guest id cards then make us to sit until they call your name. They took 1st round on day 1 then asked us to come after next 2 days and took 2nd round virtually in the campus in a separate cabin. They informed that there will be assessment round but no information yet.
