pls house does any body know about direct on pc,s structure,pay,interview and expectation.pls i need this urgent for decision.

Hmm, don't mean to burst your bubble, what position did you apply for ?
The pay range is between N25, 000 and N35, 000 depending on the position and/or skill level/experience.
They would usually expect you to have some skill level or a substantiated knack for learning.
It not a place to stay to build your career, but it can give you a good platform and they have a name you could use to on your CV.
Don't let the low pay discourage you if you can.
Cheers.
