My interview went smooth, they enjoyed that I was upfront about any prior engagements that I was currently in. They appreciate confidence and grammar. Show them that you want the job and dress to impress. Think before you answer any questions, you are not being quizzed on how fast you can answer the question but of the quality of your answers. This was a good experience for an interview, all you need to do is keep your cool, breath, relax, and answer the questions that are asked about you.
