Do you know the right questions to ask when it comes time to grow your business and hire some help, from apprentice to master plumber?

There is more to a successful interview than industry knowledge. Any potential employee must also understand and respect safety precautions, work well under pressure and as part of a team and be equipped with good problem-solving skills. The apprentice must follow instructions, while the master plumber must demonstrate leadership skills as well as familiarity with regulations and processes. You will also need to tailor your questions according to the industry, for example, are you hiring a maintenance or contract plumber?
