It's a "legit" company .... but I think scammers have "hi-jacked" the address / name,
as the tel numbers you have quoted are NOt the numbers on their site.

It would be prudent to contact the company direct, and ask them some questions regarding employment

Also, as we are all aware, recruiting workers from the Philippines is not easy these days,
so it does seem like a scam to me.

... also, the "give-away" will be how they ask for the "processing fee".
If they mention Western Union ..... then 100% a SCAM
