I will answer your questions about the meaning of life.

The real question is what is the purpose?

The natural drive of life is to live and to be happy. Our honor as thinking creatures is to pursue that drive in a way that minimizes suffering for others.

Why do people fall in love with others?

Because at its best, love is a sweet, thrilling, gentle and all-encompassing reward for living. Even the worst love is a yearning for this.

Don't join a religion you don't believe in. It'll just make you bitter and dull.

Keep at the interviews, don't be afraid to make a few embarrassing calls afterward - "do you mind if I ask you what I could have done to improve my interview performance?"

Considering I don't believe in a personal God/Christianity anymore, how open or expressive should I be about my beliefs when I know people assume/think I'm a christian?

If you enjoy it above the board, do it. If people find out you're not toeing the party line, the worst that happens is you talk about it.

because evil has a defined meaning that is dependent upon specific actions.

Huh?

because evil is defined by what the need can make us do.

Huh?

however, evil may not be wrong and I think this is where you got lost.
