I'll scream the answer at the top of my lungs: ENGLISH!
I like to cut to the chase.
Let's digress just a little...
There are two requirements every employer wants a new grad to fulfill:
1. Did you have an internship in college that directly relates to the position we want to fill?
2. Can you speak in a complete paragraph? How 'bout a complete sentence?
This last one reflects a new low in employer expectations, 60% of whom say these new grads "lack communication and interpersonal skills." You see, they don't like what's coming out of American colleges these days, and they want a new grad to at least meet a minimum standard.
Message to high school students: If you master the English language, no one is going to care that you took 5 years of Spanish. Nobody. You will come across as a genius who knows how to use an adjective and an adverb.
While in college, volunteer for every writing assignment so a professor who actually cares can tell you what mistakes you're making. That will hone your writing skills.
And volunteer for every class speaking presentation to see if you can speak English well enough. That will help with your speaking skills.
Here's another no-brainer: Stop ending your sentences with "and stuff." And never use the word "like" for the rest of your life.
