The interviewer was very friendly. The first thing he told me was to relax because I was done with the hard part. This round consisted of general questions like - 
1. What do you consider to be your greatest strengths and weaknesses?
2. What do you plan to do in the upcoming years?
3. Will you want to pursue higher education?
4. How has your journey at your college been?
5. Do you think you’re a team player? Give some instances to prove it.
6. If I were to call your friends and ask them about your biggest weaknesses, what do you think they’ll say?

Very interestingly, after the last question, he asked me to name a few of my friends and asked for their phone numbers too.
I was very nervous about if he was actually going to call them and ask this question.
