Tech Mahindra interview questions

I applied online – interviewed at Tech Mahindra (San Jose, CA) in June 2015. Interview I applied for Java developer position and it took 2 weeks for the interview process - Two Technical rounds with webex. Interviewer was good and made me comfortable to take the interview. 2nd Round Interview was like applying for Microsoft.They are expecting you will write the Code on the Notepad.They are asking like why Java follows Polymorphism.It feels like quitting the interview process in between.They took around 1:15 mins of Interview feels like fully demoralized.
