In this round for me it went 45 minutes. Initially Self introduction , then as by resume skills the questions will go on...For me 1st oops concepts inheritance and some other questions from oops . Second problem solving i wrote code on online compiler..the question is litte bit hard..if don't know means it's ok just write the logic . Then questions will surely come from your Projects. So keep updating your project details and maintain project files in ur machine .try to communicate properly and clearly that's the key for selecting this round.
