Tina's psychology curriculum required her to study an individual's personality type using the process of interviewing. She selected Darren, her brother's roommate, as her test subject. The highlighted points of her research were that Darren is a Law graduate, who is a musician in his spare time. He is an independent person who paid his way through Law school; his friends get annoyed with his impulsive behavior. According to the RIASEC model, Tina classified Darren under the type of personality dimension.
