We've seen Fidelity lean toward candidates who can connect their work to real products and real users, not just recite theory. Across the experiences we reviewed, interviewers kept coming back to resume projects, the decisions behind them, and what the candidate actually contributed. Even in the AI/LLM-focused process, the conversation centered on hands-on experience with LLMs, familiarity with architecture, and how that background maps to the team’s internal products. That tells us Fidelity is looking for people who can speak credibly about applied work in a way that feels grounded and business-aware.
A recurring theme is that the bar is practical, not performative. One candidate described straightforward SQL, Python, regression, and model-training questions, while another noted there were no hard technical drills at all, just a relaxed discussion of projects and fit. That contrast is important: Fidelity seems to calibrate heavily to the team, but the common thread is clarity. Candidates who did well were able to explain their choices, discuss data pipelines and changing trends, and reason through scenarios without hiding behind jargon. We also noticed that the interviews often leave room for the candidate to ask questions, which suggests the team is evaluating whether you’ll engage thoughtfully with the work, not just whether you can answer quickly.
The non-obvious make-or-break factor here is specificity. Our candidates report that vague answers don’t go far, especially when discussing projects or AI experience. Fidelity appears to value people who can describe the mechanics of what they built, the tradeoffs they made, and how the work would hold up in a production setting. In other words, the strongest signal is not breadth — it’s whether your experience sounds real, relevant, and easy to trust.

Real interview reports from people who went through the Fidelity Investments process.
I applied to Fidelity for a Data Scientist role on their AI/LLM team, which is embedded within their AI research lab and supports a few specific internal products. The role was focused on large language models and AI applications, which aligns with the direction I'm looking to move in professionally.
The process was virtual and consisted of two rounds.
Round 1 was a standard HR screen. Nothing out of the ordinary — basic questions about my background, interest in the role, and availability.
Round 2 was a conversation with a Senior Data Scientist on the team. The tone was relaxed and conversational rather than a formal technical interview. The interviewer walked through my resume and asked about specific projects I had worked on, with a focus on any AI and LLM experience I had. He also asked whether I had familiarity with LLM architecture specifically. That said, there were no hard technical questions, no coding, and no case studies. A significant portion of the interview was actually him sharing information about the team, the work they're doing, and answering my questions. It felt more like a mutual conversation to assess fit than a rigorous evaluation.
Overall, the process so far has been low-pressure. If you're interviewing for this team, be ready to speak clearly about your hands-on experience with LLMs or AI projects, and come prepared with thoughtful questions about the team's work — that part of the conversation took up a meaningful chunk of time.
Prep tip from this candidate
The Fidelity DS interview (at least at the senior DS screening stage) was almost entirely a resume and project walkthrough focused on LLM and AI experience, not a technical coding or case study round. Come ready to talk through your specific AI/LLM projects in depth.

Synthesized from candidate reports. Individual experiences may vary.
A virtual recruiter or HR screening call to review your background, interest in the Data Scientist role, and availability. This stage is mostly introductory and helps confirm basic fit before moving forward.
A conversation with a Senior Data Scientist or team member that walks through your resume and past projects in detail. Depending on the team, this can include basic SQL and Python questions, rapid-fire data science fundamentals, or discussion of AI/LLM experience and familiarity with LLM architecture.
A second-round interview focused on practical problem solving and how you think through real-world data science work. Candidates may discuss model training, regression, code review, data pipelines, and scenario-based questions rather than heavy coding or algorithmic challenges.
