Pros
DRW is a place where I was able to expand my knowledge in both systems and industries. I would certainly not use the word 'empowered' but I felt as though my job was important and that was communicated to me regularly. I had a great relationship with my boss for the most part and the open environment encourages and assists with inter-group collaboration. I had the freedom to make suggestions to anyone, explore ways of making processes better and then acting on them, and working with a multitude of people across various departments. As mentioned in other posts, the benefits and pay are amazing - inclusing of free breakfast/lunch, massages, wine tastings, unlimited snacks/drinks, and an awesome bonus package (relatively speaking). I also found a solid work-life balance and was supported in various opportunities to further this effort during some personal situations.
Kontras
A lot of the reviews on here say the firm is bloated, which makes it hard to advance (and also depends on who you work for in which area of the firm). I would tend to agree with all of these sentiments. The advancement opportunities are slim to none and the communication from the top down is poor (two of the main reasons why I left). Although management brags somewhat about an open door policy, there are a lot (and I mean a lot) of closed door conversations and decisions, ultimately diminishing employee trust and morale. Someone else referred to huge egos and politics citing a poor follow through on their "no a**holes policy" -- couldn't agree with that more.
