Masters Degree in Arch, but dont want to be an architect

My goal is to work for an interiors team for an architectural firm. I love architecture, but i truly believe interior design is alot more enjoyable. I have an accredited undergrad in interiors and im wondering if i should get a professional masters in arch, im not trying to be an architect, but i was wondering if an architectural edication would help get me into the bigger firms i want to work for. Im only 21 so i really dont see any harm in doing 3 years of school if it will boost ny career prospects. Cheers via /r/architecture http://ift.tt/2uR3J7z
