Hello, Mr. K G Vishnu, according me there are no genuine home based bpo or kpo jobs as it is my experience where I had seen many of the companies who are offering these types of jobs charge some fees to become a member of their group and then, after paying them they give your mobile no. in the newspaper advertisements, and after that, as I have seen the ads and paid the charges to them, the people who are interested will pay and you got a small amount of commission for that. There is no types of bpo or kpo's are involved here. As you just receive the calls from the advertisement viewer. And you also need to do the hard task of telling them the address of the office every time where they need to pay or sms the address to them. If you want to try for bpo's then why not you directly go for a walk in interview, there are many companies who gives us oppurtunity to work with them. And if you don't have such information about this companies, you can post your resumes to job seekers site. So better be aware of this type of companies who are charging people for doing nothing.
