Hari Om. As far as I have gathered knowledge, concept of Iswar Prapti is different in different minds.
Some people believe that, having an interview with God is Iswar Prapti, or calling God whenever needed is Iswar Prapti, and so on.
I want to say that all are correct (in their levels of belief) on this concept.
If you make your concept clear, then there will be no doubt of what will happen next. In order to make your concept more and more clear, you can read the biographies of saints who have attained Iswar Prapti like Gorakhnath, Chaitanya Mahaprabhu, Adi Shankaracharya, etc. There are even many who continue their normal day to day life without being recognized by the society, that they have achieved Mukti.
