As a junior I’d much prefer a whiteboard where I just need strong CS fundamentals and reasoning to a work sample where there are 10+ different dimensions I could be judged on like style, maintainability, whether I used the latest language features, how I solved the problem ( use libraries or from stratch?) there are just way too may variables and potential bias in the judges VS did you correctly turn the problem in a DP algo.

When I was a junior, I didn't have strong CS fundementals! But I had about 5 years more practical coding experience than most juniors.

Ideally you would be given guidance on what they will judging you on.
