The code pairing round is the part of the Thoughtworks software engineer interview that candidates describe most often. Candidates report being given access to a code repository or a live problem and asked to implement a feature while the interviewer watched how they structured, refactored and tested the code. Interviewers reportedly care about how you explain your choices, with OOP design, naming, inheritance versus composition and unit tests coming up repeatedly. One candidate reports a test-first expectation, and another was asked about TDD familiarity in the recruiter screen. Interviewer style varies, and one candidate found the session more directive than collaborative.
The technical round usually centers on your own work. Candidates describe walking through a past project's architecture, a cloud migration, or how deployment worked end to end, and CI/CD pipelines came up in two reports. Expect follow-ups that start from your resume, so be ready to go deeper on anything you list, from SQL and database design to language fundamentals. One candidate also reports a HackerRank-style assessment with four easy function-writing questions before the pairing round.
The later rounds are about culture and leadership. One candidate describes behavioral and situational questions on teamwork and adaptability, and another a leadership and decision-making conversation. One candidate with a different engineering title reports a final client-matching conversation that ended in rejection despite positive technical feedback. Outcomes in the reports are mixed, and most describe the process as collaborative rather than adversarial. One candidate found the post-decision feedback hard to reconcile with the interview, so ask your recruiter about next steps and evaluation criteria.

Synthesized from candidate reports. Individual experiences may vary.
Candidates report a recruiter or HR conversation first, typically covering current work, tech stack, agile and TDD familiarity, and sometimes compensation or sponsorship status. One candidate describes it as about 30 minutes. Another was asked basic OOP and SOLID questions at this stage.
One candidate reports a HackerRank-style test before the interviews, with four easy function-writing questions. Others do not mention an assessment, so it may vary by role and location.
Candidates report pairing with an engineer on an existing codebase or a live problem to implement a feature. Reported focus areas include OOP, naming, inheritance versus composition, unit tests and test-first work, and explaining trade-offs aloud. One session ran about 1.5 hours, and interviewer style varies.
Candidates typically describe a conversation about their own projects, including architecture, cloud migration, and sometimes deployment pipelines, SQL or language fundamentals. Follow-up questions often start from the resume, so be prepared to justify why you made each decision rather than only what you built.
Candidates report a final culture or leadership conversation covering teamwork, adaptability, decision making and how they handled past situations. One candidate with a different engineering title reports a client-matching conversation that led to a rejection despite positive technical feedback.
