Please go through the open threads here to understand how it works.

Always remember if you come here under visit visa then leave the country on 29th day in order to avoid penalty and ban. Good luck

Your post is not clear. You came to Singapore with an approved EP, but did cancel it after arrival and applied for another job instead? Why?!?
In most cases, EP processing takes longer than 15 days. So you will have to leave Singapore temporarily.
