Passage
I'm glad we had a chance to conduct final interviews with the two candidates
for the Muscle Power Protein Shake sales position. Before we vote, I'd like to
share some observations about the first candidate, Tom Tom seemed a bit
modest during the interview, not wanting to speak up about himself. But when
he did finally get going, he was overly complimentary about his own
accomplishments. In addition, I should add that this is a sales position, so
much time will be spent interacting with customers. As far as personal
appearance, Tom is quite slender, which could be an issue, given the product
he's selling. So, you could say I was underwhelmed by this candidate.
