Pros
Intelligent people, good and efficient processes. Salaries are reasonable and there is a good benefits package including a new work laptop, paid home internet access and snacks and drinks supplied in the office. Lots of travel involved if you want it. The more experience you have, the more you can move around with ThoughtWorks. However, if you're in high demand, you might be asked to travel more than you bargained for. Most of the time though, resource management caters to the needs of those who want to stay in their home city or those who want to travel more. There is also an annual weekend away to a location in your home country with all offices in that region.
Cons
Lots of people with strong opinions, which can be a good point as well. Although you can learn a lot from the bright minds at this company, sometimes you can feel overwhelmed by the fact that everyone has such a strong point on view on any such topic. There can be a lot of stubbornness as well. This can result in an arrogant workplace where your colleagues don't acknowledge that they have to work within the existing frameworks before they can truly 'revolutionise IT.' The working hours are sustainable, although the job requires more than just your standard hours at work. Most people are also involved in lots of 'after hours' education and learning which means it can be difficult if you really want to maintain a good work/life balance.
