Praetorian warrior

Accept a challenge and test your problem-solving skills with our Tech Puzzles. Solving the puzzles could give you a head start if you want to be part of our team - Enjoy!

To become a Praetorian you will be expected to demonstrate knowledge, persistence, honor and integrity. We have constructed a series of challenges, for those who wish to prove, test or hone their skills "on the field". The reward for successful completion of the challenges is an interview with the Praetorian Tribuni (senior members), for consideration of your application.
