HCLTech Customer Service Representative interview questions

The interview should have started at 10 max but it started at 12 , we were told to arrived at 9 and waited till 11 at a auditorium and was shifted to another place for the interview . At first we had 2 small interviews to access our communication . After that we had to talk a voice assessment ( valent something test ). And they told us to have lunch and when we went for lunch , I was called for the next interview so I finished up quickly went to attend the team lead interview < he basically asked situational questions , talked about salary , it was a chill convo > , it was 4 30 something by the time . I was told to wait till 6 for another interview but i had to catch a train for my home back so I asked for a virtual interview. I had interview the next day and it was okay . What could they even ask for a customer service role
