vIPtela interview questions

My first round went well with hiring manager and was called for F2F with 6-7 more people which went extremely well. I cannot think of any question which i could not answer, just that I didnt had networking experience which everyone was aware of. After interview, I sent followup email to hiring manager as well as coordinator from who I didn't hear anything, after couple of followups, the coordinator told that I am have been shortlisted for final interview again and will hear back again. I didn't hear anything. I again sent followup mail to hiring manager, coordinator as well as HR and none of them even have courtesy to reply or inform me. I understand if people are not selected generally they are not informed but I think if a candidate followup at least he should be informed about his candidature. Its really very disappointing!! would not recommend this to anyone I know.
