Ramrise has a valid point. We are all different.
Hands Solo has explained graphically what you WILL be doing as a junior Airbus FO.
If you are OK with this, go ahead and apply. I hope you succeed.
It is most probably easier to deal with this sort of lifestyle when single with no home ties, children etc. Perhaps I should have aimed my original post at those who have an established position in another company, and have a family at home. There is more to give up ( eg current seniority ), and more to lose if it doesn't work. This is when the decisions get harder, and involve more people than just yourself. Thorough research into the position you are applying for is important, and at least now, you are all aware. Do not simply assume it's a breeze at BA. And be aware that the rules and lifestyles are different longhaul / shorthaul. Different criteria apply, and so junior 400 pilots have a little more control over rosters ( just a little ).
To all you guys in other companies...we know you can, and do, work hard too. I have many friends in the charters and regional airlines. Let's have some mutual respect for each other. We have all worked very hard to get our qualifications, and we are all good at what we do.
Say hello to another pilot on the RT one day, as he gives way to you on the taxiway.
