When should I use the subjunctive mood?

Which sentence is grammatically correct? Which sentence make sense (apart from syntactical analysis)? First? Second? Both of them? Are they patterns of conditional statement about future (if something happen now, it will have an effect in future)?

Solution 1:

"If he is polite, then he gets the job" is far more natural. You would never actually find instances of the second sentence being used, even if it were grammatically correct.

You're also mixing tenses here, so even better might be: "If he is polite, then he will get the job."
