PDT Partners
Systematic research and engineering in a collaborative, long-term culture
Source confidence: Official + candidate reports · Last reviewed: 8 Sept 2026. Exact process varies by role, office, and year.
PDT Partners is a quantitative investment firm that emphasizes research, technology, intellectual curiosity, and long-term collaboration. Its careers material distinguishes quantitative research, machine learning, research engineering, performance engineering, and software engineering roles, but does not publish a standard interview sequence. Candidate reports provide useful evidence of research discussion and quantitative or probability questions for research roles, while exact stages and formats remain role- and cycle-dependent.
Interview Rounds
Interview processes vary by role, office, seniority, and year. We separate official company information from candidate reports and third-party guides.
Round 1:Application and role review
PDT recruits across quantitative research, applied machine learning, research engineering, performance engineering, and software engineering. Preparation should follow the requirements of the specific opening; PDT does not publish one firm-wide interview sequence.
Round 2:Quantitative and research discussion (reported)
Quantitative-research candidates report discussing their previous research and working through quantitative or probability questions. These reports provide useful preparation evidence but do not establish a universal question set or interview stage.
Round 3:Role-specific technical evaluation
Third-party and candidate reporting suggests additional quantitative or coding evaluation depending on the role. Public sources do not establish a fixed sequence, duration, or round count.
