Excellent directors and congenial co-workers. You are equipped with two computers and everything else you need to do your job well. The greatest advantage is that you learn a lot, and the new skills can help you succeed at your next job. Another advantage is that you have a good deal of autonomy. No one stands over you and tells you exactly how to go about each task. In my case, in fact, my supervisor's office was in a different building and she came around only occasionally. You have decent health insurance, professional development opportunities, and you can take language courses free. There are two big parties a year and a few breakfasts and cocktail events. It's a very human place to work. I was treated well there and am still friends with some of the people I worked with.
Minpunten
The two biggest cons are the pay scale and the workload. It's a small company with below average salaries. You are responsible for doing your job well, and that often means putting in many more hours per week than you are actually paid for. (You may get a bonus at the end of the year, however.) If you are not willing to work hard, sometimes very hard, you shouldn't accept a job at Rennert. People do get fired there, and once you have received a warning, you will be severely scrutinized.
