Concentrix Customer Service Representative (CSR) interview questions

Telephone round, verbal check, talking to HR and ops round . Communication skills and fluent English and confidence must be there. Pronunciation must be prefect and tell me about yourself is the basic question.

They are not a serious company at all ,I have been contacted by them by phone ,later they sent me an assessment to do , when I sent them . They said me to send CV to make an interview so I sent again . I haven't got a reply so after 5 days I contacted them to have a feedback , they said WITHOUT TELLING ME IN ADVANCE "Your interview is tomorrow at 12 pm " and I told them at that time I couldn't because I was working, they said "find a slot from 10 am to 1 pm "but I told them again my shift work from 8-14 from Monday to Friday so that I could after 2 pm or at weekend at any time, I have never received a reply again .
