Assembler Assessment allows you to describe your preferred work style and how you work best in organizations. It takes most candidates 20-30 minutes to complete the Inventory but you will be provided up to 60 minutes to respond to all of the items. You must respond to every item. You can change your responses to an item while it is on the screen. Once you move to the next screen of items, however, your responses will be "locked" and you won't be able to go back to them.
