CON,
Don't allow yourself to get side-tracked by a few cranky posts on pprune.
You don't say what you're currently doing but its probably not RPT/Regional and this can be the most rewarding job in the world. I have been at it for over 5 years and now moving on to a major. I have had the best fun and really enjoyed my flying. Of course there are some days and some people that spoil it but comparatively speaking it doesn't even rate.
Most of the people who rant here are either running out of opportunities or would get a case of the irrits about anything. If you allow others to control your life you can feel very weak and angry.
Why don't you see if you get through all the stages and remember the interview is a two way street. If you don't get a good feeling about it.....DON'T DO IT.
