You click a link that takes you to your online test. You are given 5 hours to complete 4 code tests. They describe the parameters and how to use the test suite decently but the questions are a bit confusing. It's not terrible but I had trouble just understanding what they wanted me to test against as they had functions in the Javascript tests that I needed to use ( and they were definitely basing everything off of) but didn't seem to register with my code. Maybe I just didn't understand properly but I think there was something missing in the test description
