Pluspunten
Do work for P&G and other well-known companies. Marketing mix modeling is great to have on your resume and many people know who Analytic Partners is. Good rapport between coworkers -- happy hours were common and enjoyable, and people often went out and ate lunch together. Small enough that if you're a rock star you can stand out and get more responsibility although it depends on your manager because many have been promoted due to their technical skill with zero regard to the fact that they have poor people management skills so your manager may not know part of his/her job is to help you grow professionally
Minpunten
You're promised merit increases and a 20% bonus but don't get either (or a tiny fraction thereof). No tuition assistance or 401k match, and medical/dental/vision is so expensive ($200 per month for a single person) that many of us got medical elsewhere or went without. No other benefits. Oh sorry except a candy jar and fancy coffee maker in the kitchen. Only a handful of levels (analyst, sr analyst, consultant, sr consultant, director, sr director) so it can be years between pay increases. Work is cyclical and repetitive so it gets boring after a while yet people feel the need to reinvent the wheel every time vs. come up with innovative analyses. Some accounts were lost because the clients didn't see the value after the first couple of projects
