Question 1 of 23

Describe a situation in which you embraced a new system, process, technology, or idea at work that was a major departure from the old way of doing things.

"Recently, one of our team proposed that we consider adding another layer of protection to our network security infrastructure. This involved adopting a technology we had never used and didn't have a great deal of proficiency with. The team member's presentation in support of this innovation was compelling and well researched, so I approved the project with the condition we run a pilot program on a subset of our data. This proved to be successful and led us to implement the addition across our entire network."
