The ultimate showdown occurs in the Unicode 20/21 Grand Finale, where the top 10 coders from the 5 leading teams in each league compete fiercely for the championship title.

Fairlane streamlines the process of assigning take-home coding challenges to candidates, helping you minimize phone screening duration while providing a more authentic testing experience. Your engineering team often finds traditional phone screens frustrating due to issues like no-shows and audio-visual problems, which disrupt their workflow. Additionally, candidates frequently struggle to showcase their true potential when tested in unfamiliar environments. This results in vague insights from phone interviews, making it difficult to decide on the next steps. With Fairlane, you can easily send a link to a take-home challenge, granting candidates time-sensitive access to their own GitHub repository. They can complete their work using their preferred IDE and tools, ensuring a comfortable and productive setting. Furthermore, candidates benefit from all necessary integrations you’ve set up for the challenge, such as automatic test runs triggered by GitHub actions on their commits. After completion, you'll receive notifications within Greenhouse indicating that the results are ready for your review, simplifying the evaluation process significantly. This innovative approach not only enhances the candidate experience but also allows for more accurate assessments of their skills.
