Only certain people have access to the data base from where names are pulled for interviews. Once your application is in the system, the best way to get noticed is to update your application. This will allow your application a better chance of getting viewed. Think of it like this... You walk into the recruitment office for a job with one hundred applications stacked on the recruiters desk. One hundred applicants applied for the same job, but only ten applicants go in everyday, take their application from the pile and place it on the top. This will greatly enhance your chance of the recruiter viewing those ten applicants over the other ninety just stuck in limbo on the bottom. Assuming your application is competitive at the time. The kicker is there is no way of knowing if your application had been viewed, then passed on. The other way is your name was specifically searched for from a job fair, Bluedart, or other means to be pulled for an interview.
