Welcome to your interview.
The question is on your right: Present Your Thesis as Execution. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
You worked on a master's thesis that involved meaningful technical execution, not just research ideas. Assume you are explaining it to an interviewer who wants to understand how you planned the work, aligned with advisors or collaborators, handled quality risks, and drove the project to a concrete outcome.
Discuss your master's thesis, focusing on how you executed it end to end.
