Pros
Some of the most inspiring and intellectually stimulating conversations I had in a work environment.
Cons
ThoughtWorks proclaims to stand for so much but most of it is fake. Their claim to technology leadership is granted by only a few smart people in the organization. ThoughtWorks' desire to work within challenging and technology leading organizations and transforming falls by the wayside when leadership is managing to utilization & large multiyear engagements with a few clients rather than truly innovating with the industry's best. ThoughtWorks has an impeccable reputation in the market and can attract especially younger talent from universities but lacks in attracting and mostly retaining lateral hires who have significant industrial expertise in either business or technology related functions and roles. Not going through the infamous ThoughtWorks academy means that you may never be in the club at ThoughtWorks and you're truly a consultant/resource and as long as you're billable - your career growth or the idea they want to articulate of having a say in being sent to desirable clients & projects is simply wrong. Over the last months ThoughtWorks has been hemorrhaging with an attrition of 20-35% depending on location - losing many of their best consultants mostly for two reasons: 1) TW pays around 20-30% less than the industry average and supposedly makes up for that through culture and benefits 2) the overall changing company strategy and the support for individual growth is suffering. Many people think ThoughtWorks is a consultancy and many people simply resign due to changing lifestyle or being sick of traveling etc - but to be honest - as much as it is a valid concern, other reasons are at play here. Additionally, within the just close to 2 years that I was at ThoughtWorks the amount of talent has significantly reduced. People are still being hired but not at the level that the industry once appreciated TW to be at.
