[Moved from]: Working for Premium Writing.com?

Anyone have experience with this company? I haven't really found any information other than a ESL writer that was charged with plagiarism but claimed he did not plagiarize. I recently got an email to write an essay for them to prove that the writing on my resume was mine and to work for them. Is this a legitimate company? I am located in the United States by the way and currently a Senior History student working on his Honors Thesis.
