Karine just did really well on her interview to work at a tech start-up company. If Karine is high in conscientiousness, what behavior would likely explain why she did so well interviewing?

A) She had a lot of energy and enthusiasm.
B) She expressed optimism about her future.
C) She spent time before the interview researching the position.
D) She maintained eye contact during the interview.

Individuals high in conscientiousness are typically thorough, careful, and diligent. They tend to prepare well for tasks, including researching and planning ahead, which in the context of an interview, would likely contribute to a positive outcome. Choices A, B, and D, while potentially beneficial in an interview, do not directly relate to the trait of conscientiousness as much as thorough preparation does.
