Hi, First of all, we would like to thank you for your feedback - we take every feedback into consideration in order to learn and improve our recruitment process. We would like to address the issues you raised: * Each home task we have is estimated to take between 3-4 hours. In practice, it might change according to the candidate's knowledge and experience. * We are truly sorry for the confusion regarding the required technologies. React is absolutely not required for our Senior Backend Engineer position, but for the Full-stack position. This was an honest human mistake made during the phone conversation. We will try to do our best to make sure this will not happen again. We wish you best of luck in your job search. Vered Shani, Director of HR
