It says there that I will need to bid at least 1 eth in order to secure a job that is supposed to give me money in exchange for my skills alone. Why is this so? If I'm looking for work, I don't want to pay money upfront to receive said work. How is this site named working for bitcoins when I have to have some money first before I can start working? 
Also, that 15 ETH posting for a data entry job is sketchy.

You are Bidding on the Job, when bidding on a job, you are indicating how much you'll charged to do the work. This is different than bidding for an item/product/service, where you are indicating how much you will pay for it.
That makes sense. I tried sending my bid and see what comes up with the offer. I'm interested in knowing what kind of jobs are there that is legitimate and is worth of my time since I literally just work 20 hours a week and have a lot of time to burn somewhere else.
