Neotas interview questions

HR informed there will be 2 tech rounds and 1 HR round, after clearing first round I was interviewed by COO (HR round) it went well, we even discussed my joining location and date. But COO was not believing why I want to join their company leaving my current one (I believe) he kept asking why are you looking for change, I answered with Growth Opportunity but he kept digging not growing in current company? you will leave (Neotas) soon too etc.

Wia awign my interview arranged with Neotas. They arranged the technical interview. Neotas manager didn't had proper internet connection, joined twice still same, hole interview was sorry i can't hear you then screen freezing and all.
