I worked through 199jobs.com and tolerated 199 taking a massive 20% cut from hours of work for a meager fee.
I also found the company would delay payments to clients who dared ask about their payment process. If you make a mistake like talking directly to a client make sure 199.com is not holding your cash, they will not pay you for your hard-earned pesos.
Bad experience all around and I would advise any would-be freelancer to explore other avenues such as online jobs ph were you will be treated professionally and you can negotiate your fee directly with the client.
Unfortunately, 199jobs.com is only interested in your money, not your future. Think twice and increase your earning potential exponentially.
