Firstsource Solutions Customer Service Associate interview questions

The interview went really well , the HR team were really helpful . They had an Assesment to check our fluency in English Langauge , then I had an interview with operational manager , again there they asked me very basic questions , they also asked me to speak about any topic , Basically you just need to speak , speak and speak fluently about any topic , it will convince them , I got selected in this round aswell . Later I will given the offer letter, but due to personal reasons I had to give up this job , So I turned down the offer letter .
