If you are being formally interviewed, you can expect that an interviewer will take some notes. In some instances, and depending on the level of the job, they will take lots of notes and then grade your answers after the interview. Employers use this standard method to help them remember whom they’ve interviewed. If you structure your answers using the GOS method, you will have included all the necessary information. If you can enhance your answers with results (i.e., numbers), that will help to improve your score.
