      Project quality depends very much on client sophistication

      Data science consultant
      Recommend
      CEO approval
      Business outlook

      Pros

      - very smart and sharp colleagues - rigourous work attitude

      Cons

      - long working hours (60h per week is normal and expected) - pay is not that high to make the long working hours worth it - colleagues don't even blink when scheduling meetings past 8pm - engineering quality of work not as high as the impression I have externally - infrastructure capability depends very much on the client, in Asia, not much cloud usage - clients in Asia are relatively unsophisticated, hence work is not as interesting as compared to those in Europe or USA

      Bad Company for Engineers

      Data engineer
      Recommend
      CEO approval
      Business outlook

      Pros

      * Good Pay (though pay-per-hour is not) * Lunch provided * Smart people all around

      Cons

      QB is trying so hard to compete with other IT consultancy to deliver large scale data platform for analytics use-case. The problem is, it is lead by a bunch of MBA grads from McKinsey who doesn't know anything about proper software engineering process. As a result, engineers are led by non-technical people which forced an unrealistic deadline, resulting in overwork and low quality of code. This can actually be solved if QB sticks to what has been its forte all along, advance modeling and analytics. I think majority of DS will be happy in this environment (which mostly happened only in London HQ). But for DE, and especially if you are not based in London, don't expect the same level of excitement in your work.
