  Hello Sohail, After the registration you will get an email will all the instructions and you will be able to view all the contents of the site. It takes about 24 to 48 hours, since it;s manual process validating the extended registration to make use the content most effectively.

You will need to regsiter only once not 3 times, you can choose from normal or extended regitration depending on the access you need. Please read getting started from the main menu.

Thanks for your comments,

  If you need to be spoonfed and require answers even for those questions then you are unfit to be interviewed. Its acceptable if u dont know the answers, you may use google and find the answers and if you dont know even that much and need canned answers then you are totally unfit to work in that field.
