Which job? If you mean HubPages, it's not a job... it is a way to earn money so it's a business opportunity, but it's not a job.
People have had different rates of success. Some people never made anything-- never got a single payout. That's not because HubPages don't 'work', though, it's because the person didn't manage to make a success of their efforts. Either their writing/hubs were substandard, they were unable to get attention for them, they didn't bother to market them/didn't market them successfully, or they gave up too quickly.
There are some people who figure out what works-- how to write not only quality Hubs, but Hubs that people want to actually read; how to promote your work and draw an audience; how to keep up momentum and continue to build. For those of us able to do that, HubPages can become a decent source of income. Maybe not enough to be your sole source of income, but I know from personal experience I'm making a few hundred a month off my hubs, so it's a nice little chunk of my income.
It's always nice to get that deposit at the end of the month, but it didn't happen without effort, nor did it happen quickly. I'm glad I put the effort into it though, as now it's paying off. I would not suggest going into it looking for big paydays in the next couple of years, though. You might get lucky and have a Hub go viral, or you might get lucky and soar; most likely though it will require an investment of serious time and effort before you're able to get something out of it.
It's also not a blogging platform; it's an article platform. You can blog, but the structure is not well suited to blogging. So if you're looking to blog you might want to reconsider if Hubpages is the best option.
