I have a MS in Mathematics and am working as an analyst for about the past 4 years. However, my job has tended to be light on the analytics and much more heavy on the business and managerial side. I appreciate that experience, but I overall don't find my work to be intellectually stimulating. I worry that since I haven't gained significant analytics skills, my next job may be more of the same. I am considering going for my PhD, but I wanted to get opinions as to the feasibility of finding an intellectually rewarding and stimulating job with my current education and lack of rigorous analytical experience. I would also be interested to here suggestions of other training routes that would serve the purpose but be much less time intensive than the PhD.
