I had a lot of hope going into MRM Detroit. However, I quickly found out that the company was incredibly bureaucratic and disorganized. In the 6 months I was there, I had almost 0 work to do. I would spend days in my office where no one would talk to me, or even acknowledge my presence. I spoke to my manager several times, always leaving with the promise that work was coming in soon. I met with HR to see if I could move to another department, and was told that I had to wait one year before transferring. My manager reassured me repeatedly that my job was secure, things would improve, and that he did not want to lose me. I decided to wait it out the year, and see about tranferring. Unfortunately, 6 months in, after multiple reassurances from my manager and HR, I was laid off. I wasn't surprised, but disappointed that they worked so hard to mollify me, only to turn around and let me go. Had they not assured me that I was safe, and that things would either improve, or I could transfer, I would have been out of there much sooner.
Overall, my experience with MRM was incredibly negative. It seemed to me that they were so large, there was no way to address individual employee issues. Additionally, they hired with no real need or role identified - instead, choosing to "take talent off the market and away from the competition in the hopes that some role could be worked out" - this is something my manager told me straight out. While the culture in other areas of the company seemed to be much better, my only real impression of MRM is negative.
Before accepting an offer at MRM, be sure to ask questions regarding the workflow. I assumed they hired me because they had a need, and I was sorely mistaken. I wasted 6 months, with nothing to show on my resume for that time.
