I applied online. The process took 4 weeks. I interviewed at Thoughtworks (New York, NY) in Mar 2018
Interview
Throughout the entire process everyone was upfront about the role and interview process.
1. I applied online and a recruiter reached out to me. We spoke about my experience and what I was looking for in my next role.
2. Interview with a principal consultant about best practices, software development, testing and a little architecture.
3. In person paired programming with a Senior developer and a principal developer. It starts with a business case and you have to implement a solution using TDD in any language you're comfortable with.
4. A second round of in person interviews and some written logic tests. The 1st round od interviews were technical white boarding explaining the architecture of some applications that I've written, coupled with questions about decisions that I've made about the application. The second round were non-technical and based on how I've contributed indicually, part of a team and how I've led. The written tests were logic and personality. The day ended with a management interview and fit.
Overall it's long but if you've prepared for any technical interviews before, it will be pretty straightforward.
