Tell me some of your strengths

I have a job interview tomorrow. This is good news in this job market and despite how many times I've interviewed over the past 10 years, I'm already nervous. I HATE interviewing. Hate, hate, hate it. Plus I don't like to talk about it because again, when you interview over and over and then don't get the job, you really lose your hope. And honestly, I'm not even sure why I was called for this one. It's a customer service position for a company that specializes in real estate and mortgages and brokers and appraisals and stuff I haven't a clue about. They seem like a really good company and I'm stoked they did call me, but I feel like this is so not my area of expertise. I can produce a newscast for you ... or a documentary on your favorite celeb, but I've been a renter my entire adult life and feel like real estate is a grown up's game. But, I have to do the dog and pony show: do more research on the company, know their history and philosophy, pick out my outfit the night before -- professional casual pants and shirt, preferably not stained, do the hair pulled back thing, and bust out my sensible shoes. God, I HATE this! Eight years ago, I was once again trying to get the hell out of television and I landed an interview to work for an employment agency. I had ... count them ... FOUR interviews!! That's four suits, four pairs of NYLONS, eight firm handshakes and forty-thousand fake smiles! I had to go to stores I loathe like Fileen's Basement and Ross for business attire. I ended up getting the job ... and then getting fired. At least I still have the suits. So, here I go again. And I know you need to interview to get a job, but whyyyyyyy do they make such a big deal out of it? I mean, in the age of no such thing as a lifelong job and so many companies going freelance so they don't have to pay bennies, is the "where do you see yourself in 5 years" question still necessary? Oh, I know them all: what are your strengths/weaknesses, why do you want to work here, how would your previous employer describe you, what management style do you like/dislike, and I love the catch all warm up: So, tell me about yourself. Christ. Okay, my neck is getting tight just typing this.
