Tata Consultancy Services Junior Java Developer interview questions

First round was clear and after few week they confirm me with confirmation with offer and friday HR called me by monday they will give offer letter. Then suddenly they told my vendor to wait for week then they set up another technical discussion. The guy who was taking my technical discussion he was forced to taek the discussion because his manager told him i was ready at 9 but i have to call that person who called me it was 9:20 pm and the guy came with bad mood and no hi how are you , like putting his hand on his head and having bad attitude .There were no respect shown from him and HR . The few days later I spoke with Hr was telling her the truth she did not hear me and hang up on me.HR was only trying to keep his team happy becasue at Jr level you need 0 to 2 years of expeirnce . And trying to make me dissappointed . There some people who dont want that some US citizen dont get this job remeber one thing god is watching everything . ALL APPLICANTS JUST WATCH OUT AND BE CAREFULL
