Hi Deepa,
I can understand when you say you expect some answers, but there may be some reasons due to which people didn't reply to your post. Maybe those who came across it were not from the same industry you were asking about, or perhaps they did not have enough information to guide you. So, get out of the opinion that everyone here has their groups; some may have, but not all. Hope you are satisfied now.
Regards,
Himani
