1. phone call with HR. 2.technical with two Indian interviewers, they were very unprofessional, not organized. They were interrupting each other during the interview which confused me, it was hard to understand them. One of them joined without a camera and it was hard to hear him too. The questions were easy when I was answering they kept interrupting me. Which was very unprofessional. I was super nice even I wanted to end the interview.
