Continental Graduate Engineer Trainee interview questions

I applied through college and there was an online test for which they Short listed 75/85 students and called for the f2f interview. During they interview most of the people we're unprofessional and we're mocking at the students. The HR lady was very lethargic as when I went to the interview she said I'm bored, entertain me. While they are many people attending the interview with utmost tension and fear, for these people it's just a time pass. Finally they selected 6 people.

2 F2F Technical followed by HR interview. They were cool. They made me feel comfortable. It was good experience. But they kept us wait for the result for longer periods.
