Once you apply to a company for a particular vacancy, your pH score and your entire profile is visible to the company. Companies will shortlist candidates on the basis of their requirement.
If a company shortlists you, then you will receive an email regarding the same, and your status in "Jobs" section changes to 'Called for Interview'. You can either decline the call or accept it, and attend the selection process.
The selection process could consist of tests, Group discussions etc and not just the interviews. The status Called for Interview is just a placeholder.
