Pramati Technologies Senior Java Developer interview questions

I applied through naukri.com. I got a mail after few days of my first round . There was 1 telephonic screening followed by 2 technical rounds and 1 hr round. They used to communicate through mail only. There was 1 scenario when interviewer didn't join the call and there was no updates from team. When I tried to reach them, they didn't respond. After few days, I got a mail for the same round again.
