I had an interview with a pharmaceutical company (for an intern position) and at the time I didn't really care whether I got the job or not so I wasn't nervous at all and consequently, I did a phenomenally good interview. I just spontaneously became highly charismatic and said everything I wanted to say. The interviewers seemed to like me a lot. I looked into this company more and now I see that this would be a brilliant company to work for. I know that they interviewed heaps of people for this position though and a lot of the people they interviewed had better marks than me last year (we had to put last years marks on our CVs). Its likely that I did a better interview than anyone else but will the marks on the CV be more likely to be what determines who gets the position or not?
