What do you think if someone has been told by the HR that you are selected & no information after that…?

Well if someone has been Jobless for almost 5 months & gives an Interview in Reliance Life Insurance & the Reliance HR informs after 4 Days that you are selected & then for another 5 days no info then what should happen…
Well as the HR has already said that he is looking for the Vacancy to fit the Candidate then??? Can anyone tell me does it take a lot of time?
