Booking.com Hackerrank Project Based test for Full stack role

Hello, Recently I got a challenge from Booking.com that include one project-based question. I don't have any idea what should I expect from this test. When I try to take the mock test it's basically a simple FizzBuzz question(not actually a project). In the test section, it advises me to install NodeJS and pug engine. I solved so many different kinds of ds/algo questions on Hackerrank but I don't have any idea what to expect from this one. Anyone attend this kind of test before?
