Guidepoint is a very young company in the sense that there are only a handful of employees over the age of 35. The office is small and intimate--most people know each other. Random little perks like beer in the office on Fridays at 4pm. The atmosphere is very high-strung and tense. Everyone is in competition with one another--employees are pitted again one another in order to optimize performance and results. Employees generally eat at their desks and breaks are definitely not encouraged. Not a good working environment.
Guidepoint is a very young and lively office -- the majority of your coworkers will only be a few years out of college. From what I saw, the work-life balance is pretty good especially for the entry level Research Analyst position. People didn't seem to work outside of 8:30-6:30 before they were in a Manager role. There were also snacks all day which was a plus. The company has a few big parties throughout the year and also covers team dinners. A few downsides: some days would get to be a little intense if projects weren't working out the way that your clients wanted, and sometimes the monotony of the work would make the day drag
