Tech Mahindra Sr. Software Engineer interview questions

Interview process took a lot of time. Candidates have to wait for hours together for First round's feedback. Your Resume is numbered as per your order of arrival at the venue, but that doesn't help i guess cause people arriving after you might get a chance to interviewed before you. HR contact person was ready rude to the candidates, very disappointing. Shortlisting of Resume by Job Portals Total 3 rounds First Round : Technical Second Round : Techno Managerial Third Round : HR
