Granting a Power of Attorney i.e. POA does not mean you cannot get the job. As a POA you will be empowered to do certain acts on behalf of the Proprietor. But you can work in the company on any position, POA can be given to the person working in the firm, family member or Thrid Party also.
So being a POA Holder is completely different and does not obstruct your employment in the firm, in any manner whatsoever.
