Concentrix Customer Service Representative Customer Service Representative interview questions

First, a few weeks prior, I received a phone call from a recruiter inviting me to come in for an initial interview. When I got there, there were people coming and going. First-round was a group interview--mainly talking about yourself. I believe they just test how well you can converse in the English language. 2nd-round if you pass, you would have gotten a first congratulation letter saying you qualified for the next round. This is when the interviewer showed a picture and I am supposed to explain what I see in the picture. Again, this is a group interview. If you pass this round, again, you would have gotten a letter saying you passed this round. Third-round was a technical computer test, this is just to know how well you know basic computer skills. The fourth round was a one on one interview. I was asked about why I left the company and what I expect with this company. The interviewer said they need a few days to decide and asked me to come back the following week. I came back and got an offer and the same day was a contract-signing.
