I have enrolled Resume flash for 2 weeks now. My findings are below-
i. Same JD postings mails comes to you but come from several consultant for same position, so no use. I would have received the same from naukri.com itself.
ii. A typical business model which goes after your wallet.
iii. In 3rd and 4th week it didnt find any job mails based on keywords but I can find it within Naukri several relevant postings.
