I agree with the above comments.
I was fortunate enough to make it through a sponsorship programme so didn't have the same struggle that most people have to get an airline job. But the only wise thing to do is to take what you can get until you can get something better. Getting your foot on the ladder initially is the most important thing.
After a while other opportunities and better living conditions / pay come along. I'm not sure how it works in other airlines, but at BA there are a significant number of pilots who work part time and they still earn very good money. And after a while when you get more senior you get much more control over the work you do. So work life balance can be very good.
Hope it's helpful in some way.
