First of all people will entertain you when you approach them personally. I did the same thing, Pangulf was one of them companies where is visited personally. I met the sales & BDM n delivered my CV. He coordinated with HR and arranged and interview after a week. Interview was quite competitive and challenging for me. Its is never easy to tackle and answer Sales Managers of big companies. Anyways i think interview was good. Since i was having the experience and records in the same field simultaneous my interview performance was good, they offered me a full time job. After getting into job i realized the working environment, ethics & culture was really good. Staff was so supporting. They make a real professional.
