Employees at Hitachi Aqua-Tech appreciate the friendly and supportive colleagues, as well as the company's quality products and opportunities for learning and training. However, there are some potential challenges, such as issues with management including a lack of direction, differing opinions among managers, and a tendency to pass work down to junior staff. Additionally, employees have noted limited support provided for overseas assignments, leaving them feeling underprepared to deal with clients in those situations. There is also a need for better recognition and rewards, as workloads can be high.
