Find a Job is Tough

First, work on your writing. I'm going to guess that English isn't your first language, but if I read that post as something from a potential hire your info would end up right in the shredder.  My writing is crap as well.  A trick is to sit on writing for a few hours and come back and read it to yourself, preferably out loud.  Even better is to have somebody else read it.  I've got a couple friends who know absolutely nothing about finance that humor me.  For 95% of my public writing I want to write to their level.  I only demand that they don't sugar coat things and tell me where stuff is confusing or too technical. (or crap)

EDIT: someone who doesn't want to hurt your feelings is possibly the worst person to proofread here.  You need to know where the problems are, so never let your mother do the proofreading.  If you don't find out what's crap in this process, you'll find it out while interviewing.  About the only bigger f***-up is to find out after a live national TV broadcast. (Yeah, a boss did that once with a painfully basic fact) 

You can get away with a lot more in an interview.  You are expected to know the company and position in broad terms, but a big portion of it is to see how you act off the cuff.  One summer an intern completely melted in an interview.  You could make an argument that he was the most qualified, (and a diversity hire) but questions like "why do you want to be here?" and "what do you want out of this internship?" completely stumped him.  He was a math major but after that he gave off the vibe of barely even being able to spell finance.

You need to do really poorly to be told so in an interview.  I did it once right out of college, but I didn't even tell the potential intern that we laughed at how badly he did.  Don't take most advice at face value in that room. Most people have liability risks limiting what they say.  Just try to read the room.
