I've been headhunted by ThoughtWorks Deutschland in September 2018. 1. Short 30 min conversation with HR. 2. Given home coding task for Pair Programming online Interview prior 1 or 2 days to it. 3. Pair Programming Interview (1 hour) online. 4. On-site Interview Day - half a day. 4.1. Technical session to work on agile dashboard with Senior ThoughtWorker. 4.2. Cultural Interview which is free-form conversation with 2 people. 4.3. Technical 1-on-1 interview with Principal ThoughtWorks Engineer. The big bet that company made is on cultural development and support as the result I was feeling very happy during whole interview process and I think they're great company and great people - even I didn't get an offer but was very close to it :-) This is definitely the company which others should learn from. Some people think that their cultural development is too fanatic & crazy, but I think it's a case where fanatism is much better than 90% of companies who has very poor culture. Besides that I am changing interview difficult to "Difficult" because I think it was "Average" but in fact if you will not answer some questions you will not given an offer. Must haves: 1. TDD & co. school - be able to code lively with TDD in mind and good OOP design. 2. Be prepared to all general Computer Science / Practices questions. 3. Microservices - be able to answer questions how to build architectures for projects. Build Microservices book from ThoughtWorker Sam Newman will fill you enough with answers.
