"In-Tray or In-Basket Exercise
In this exercise you will be asked to assume a particular role as an employee of a fictitious
organization and to work through a pile of correspondence in your in-tray. The in-tray
exercise items will be specifically designed to measure job skills such as: ability to
organize and prioritize work; analytical skills; communication with team members and
customers; written communication skills; and delegation.
The in-tray exercise is popular because it has considerable ‘face validity.’ In other words,
candidates can see how it relates to the job they are applying for and therefore they tend
to take it seriously.
If you have not practiced an in-tray exercise before it is very easy to be overwhelmed by
the amount of material you are expected to work through in the time available. At the
very least you should practice working through items and classifying them according to
their urgency and importance. You will invariably find that there are one or two ‘major
issues’ hidden among the in-tray items and if you miss these you will struggle to remain
a credible candidate. "

How do in-tray exercises work?

The basic idea of in-tray exercises is to place you in a realistic although simulated work situation, and to assess your workplace behaviour and attitudes in that context. So when you’re given an in-tray exercise, it’s usual to be asked to treat it as a role-play. You’ll probably be asked to imagine that you’re an employee of a fictitious company, and to work through the contents of your in-tray in that role.

You might, for instance, be told to imagine that it’s your first day in your job as a stock controller, and be handed a stack of documents and tasks to prioritise and action. You might be given this role even if you’re applying for a job that has nothing to do with stock control; similarly, you might be asked to imagine yourself as a teacher or a lawyer, even if you’re applying for a quite different job. Another common scenario is that you’ve just returned from annual leave to find a pile of correspondence in your fictional in-tray. The point is that the skills and attitudes being assessed will be relevant to the job you’re applying for; the types of issues and problems you’re asked to consider will be similar to those involved in that role.
