Question about school and career progression

Hello all, I completed my B.A. in Psychology this last May, and am starting a program for a M.A. in Industrial and Organizational Psychology in 2 weeks. Basically my question is, how do I break into the field? I know I/O is a relatively specialized field but I do not want to wait until after my M.A. to begin working. Even then I'm kind of confused about the process. What am I now qualified for because of this M.A.? Is there any tips or kinds of places I should try to work/volunteer while getting my Master's to put me ahead of the game when I graduate? I was trying for HR/Talent acquisition, but am not really qualified with just my B.A. I'm currently looking into IFC certification and PHR certifications. Thanks!
