Very smooth and professional. The interviewer was nice and respectful. Just be confident on what to say and what to answer during thw interview process. Be firm to what you are answering and be straightforward

(initial interview) It was very light. If you have no experience with BPO or Call Center, they will only ask 3 questions: How would you handle tension with teammates, how do you handle pressure, what will you do with an irate customer. Sort your ideas and don't speak fast. If you are experienced, you will get more questions regarding your background.
