According to All About Careers, commercial experience refers to having knowledge of working in a business environment. Commercial experience increases a person's ability to view situations based on a business perspective.
Increased commercial awareness arms a candidate with the tools needed to understand what drives a business to success. This experience becomes valuable as the career progresses. Progression usually means more responsibility and direct decision-making power.
Employers assess the commercial experience of a candidate during the interviewing phase. Often, behavioral questions are asked to determine the candidate's ability to articulate a situation and how it was handled.
Commercial experience can be gained by working and seeking to progress within a career. Obtaining a mentor is also an excellent option to help develop commercial experience.
