That is not how it works - if there are openings, the ones that are there in person will be the ones with chances. By the time you get there, the job will already have been taken. So the only way to do it in this region of the world is to show up and stick around like everybody else. But even that has been said a thousand times in this forum. Positions are generally not advertised, there is no need for companies to do that, as there are always enough low-timers sticking around to get in.
