"The questions you are asked in an interview for a position as a scientist will depend greatly on field of science you intend to work in. Generally, interviewers will be interested in your formal education, field of study and specialization, work, internship, and research experience, scientific writing skills, and interest in the subject matter. Expect to be asked technical questions that pertain to the knowledge needed to perform the duties of the job. While there are some positions open to scientists who possess associates' or bachelors' degrees, most jobs will require you to have at least a masters' degree with the majority requiring you to have a doctorate."
El examen técnico te da un pequeño conjunto de datos con características de autos y su consumo en combustible. Te piden predecir el consumo de combustible y predecir las clasificaciones de los autos. El examen de confianza te hace preguntas tipo "¿qué es peor, violar a un niño o envenenar a una ciudad?", "¿con qué te identificas más: 'mi mala salud me hace infeliz' o 'me detesto a mí mismo'?". Quién sabe cómo lo califican o cómo concluyen de ahí si eres bueno o malo.
