The assessment vendor will screen you for how well you communicate. So keep an ear out for any stutters, awkward pauses, or your use of any speech crutch words such as "uh," "like," "um," "you know," "so on and so forth," "and," "well," "but," "so," "ah," "er," and "Etcetera." Record your voice while answering some of these questions to identify your tics so you can better practice answering these questions without relying on such words. Also, pay close attention to your choice of words and what they might suggest beyond your intended meaning. Doing so will aid in presenting yourself as a clearer communicator and more of a professional.
