As an HR expert, I understand that the phrase '回家等消息' can be frustrating for candidates as it may seem like a vague response. It is important for HR professionals to maintain clear communication with candidates throughout the recruitment process. While it may not always be possible to provide immediate updates, it is best practice to inform candidates of next steps and timelines. This helps to manage expectations and shows respect for the candidate's time and effort. Therefore, it is recommended that HR professionals notify candidates of any decisions or updates, even if it is just to let them know that there is no new information at the moment.
