The process for interviewing for a job is similar to the dating process. Generally, it goes something like this:
Step 1: Find someone you want to date (find a place where you want to work)
Step 2 (optional): Find someone that might know her (find someone that might know someone who works there)
Step 3: Ask them out (apply for the job)
Step 4: Go on the date (go on the interview)
Step 5: Get rejected (… get rejected)

The process may be similar, but the details of how you should conduct yourself are completely different. Interview behavior and dating behavior are exactly the opposite:

Her rejection goes “don’t ever call me” and that’s final.
Businesses rejection says “not now, but better luck next time”. Next time!? Yes. There can always be a next time.

If you call all the time to ask her out, you’re a “stalker”.
If you call a company all the time, they call that “persistence”, they call that “following-up”. Just be courteous.

If you hit on her and then hit on her friend, and then hit on her friend’s friend, you’re desperate.
In business, they call that networking.

If you date her and then date her friend the day after the break up, you’re a jerk.
If you work at a company and then work at a subsidiary, you can work for both places at the same time.

If she dumps you and you’re no longer in a relationship, you might get a bucket full of drama without any benefits.
If your company dumps you, you might be unemployed but you get zero drama and a bucketful of benefits.

When going to a restaurant and the bill comes she won’t even look at the check, you’ll pay.
When you eat out with business, they always get the bill.

During a date you may want to flirt, touch, hold hands.
Do not, under any circumstance, run your fingers on the back of your interviewer’s hand.

Never talk about your past on a date.
Most of your conversations is about your past on an interview.

Powerpoint on a date. WTF.
Powerpoint in an interview. Ooooh, impressive.

Asking your date if she’s willing to make physical augmentations, like a boob-job, will get you a slap in the face.
Asking your employer if they’re willing to make physical changes to your work-area is something to ask before you start.

At the end of a date, you’ll know where you stand, you may get a kiss, a hug, or a handshake, to gauge how it went.
At the end of an interview, good or bad, you won’t know how it went, it’s always the same “Thanks and we’ll get back to you”.
