Sounds like fun I signed up! Question though how long does the contest run for? How many challenges are there and how long should each one take?

Glad you signed up! :) The contest is going to run for 4 hours, and there are 4 challenges. The first two should take about an hour total, with the remaining 3 hours split over the remaining harder two challenges.

The contest is for 4 hours and there will be 4 challenges. The challenges will be later archived and posted on the security track at hackerrank.com (to be created after the contest)
