I got a call from company HR who shortlisted me and asked some questions related to education and experience. After 2 days I got call from a person claiming sales HOD he again asked some question related to education and experience. after a day I got call from HR man who talk about my availability to join and CTC. By evening I got an email stating I am selected and have to come for 3 days training at their HO. I asked for the offer letter and time for putting resignation at my current company. They sent me offer letter and said to that its immediate opening and max can give a week time to join. As its a listed company so i decided to put resign and join it. (MISTAKE of my LIFE)
