Clerical Test - make sure you remember how to divide and multiply fractions.. the test was kind of brutal.. no calculator! The test was on math, vocabulary, filing, etc.
First interview - met with person who would be my supervisor
Second interview - met with supervisor again and then heat of the graphics department
Drug Test - the typical one that only tests for a few things with a urine sample
Interviews required a printed portfolio and the questions asked were basically about my education, previous job experience and a few typical questions where you would explain situations in which you didn't get along with a coworker or your boss and how you handle critiques, etc.
Both interviewers very clearly explained my would-be job responsibilities and the culture at Dart.
