A bank teller's assessment test assesses the applicant's numerical math skills, customer communication abilities, general language ability, attention to detail, coding and customer-relations situations that commonly arise in the bank teller world. Banks vary slightly in how they conduct their assessments and what they include in them, but these are the standard skills for which they are screening.
The assessment does not include technical banking information, as it rather tests the applicant to see if she has the natural abilities needed to do her job successfully. The two main areas banks focus on are language fluency and numerical ability. The language portion explores customer interaction and how the applicant would do at solving customer problems, listening to their concerns and extracting the needed information. The numerical portion tests whether or not the applicant has the basic math skills required. Some banks allow a calculator or scratch paper during the test, but this varies from bank to bank. Banks use the math portion to gauge applicants' mathematical abilities to catch discrepancies and responsibly handle large quantities of money.
Tests take around 45 minutes to one hour, depending on the applicant's speed. Some are conducted on the computer, others are paper and pencil. Banks are more impressed by applicants who show up early for the test, prepared with pencil and paper, if allowed, and are dressed professionally.
