Vantaggi
ThoughtWorks has its reputation and at times they live up to it. They have great projects, amazing people, awesome culture and it feels like a family. The training in India for grads is great, if your trainer likes you. There's space for opportunity and they're flexible if you want to do things like volunteering. The "Pillar 3" of social and economic justice is a core part of the culture and not just for show. Great teams, with plenty of team and company activities like the away days and local office days. They're really flexible on changing roles and it's more common for you to be staffed as different things rather than be pigeon holed into one role.
Svantaggi
It's not a place for graduates. "The beach", which is where you're left to rot in a corner until staffing have bargained with someone to put you on their project. Six months on the beach as a graduate with no support was not fun, to say the least. Lack of support from seniority, especially in the Manchester office. It's chaotic to say the least, especially if the slightest thing goes wrong. They under pay massively and expect a ridiculous amount of devotion, travel, work hours - including weekends. In their recruitment videos they boast how you can walk into their offices and be who you are, yet their culture of feedback rips you to shreds. A few people, including myself, have said they felt like they needed a personality transplant when they got there. My advice for graduates is don't bother and apply as a lateral hire.
