Startup Idea
So:
1- For the one who actually work for a company: When you search searching your job, did you knew someone inside? Or what they you use?
2- If you own a company, how did your employees known about you?
I say that because when you're good, it's easy to find a job. However, it might not be easy to find your perfect job since you don't know about all the company.
And now, finally, for the startup idea:
A simple "friendsjob" where you log on with facebook, and you see job opportunities posted by your friend.
Does it already exist? Would someone be interested in creating that website? :)
