Hi there, thank you for your valuable review. We fully understand your displeasure since you invested a great amount of time to complete our code challenge, which in matter of fact is challenging since we only hire suitable and talented candidates. Your review surprised us since we always do our best to provide a comprehensive feedback to applicants that completed our code challenge. Nevertheless mistakes can happen and we are very sorry that you made a bad experience with us. We will use your review to optimise our process for future applicants. Please send us an email asking for an update to your code challenge and we will get back to you in due time. Once again thank you for your valuable review and please excuse the unwished circumstances. Sherpany Talent Team
