ePayPolicy Software Developer interview questions

I applied online and was contacted by HR. They started salary negotiation from the first HR call, that was surprising. I realized they underpay compared to other interview call I was getting. The interview is of 3 rounds: 1st call with team lead, basic OO questions. 2nd call with a software dev, basic C#, .NET, JavaScript questions. Then I was never contacted by HR. After 2 weeks I contacted the HR and he just wrote that they didn't select you. Overall the way they handle candidate interviews and their salary range is not acceptable.
