Interviewing at Oak Street Health
What the process looks like, and what Oak Street Health is really testing for.
You can expect a loop built around technical evaluation plus collaboration and communication. Across roles, interview topics consistently emphasize Business Analysis (Technical Skills), PySpark, .NET (C#), and SQL, with communication and expectations management also showing up prominently.
What you are really being tested on is your ability to translate requirements into data work, then demonstrate practical analytical skill using SQL, interpret results, and reason about how data moves through systems. The topic mix also shows data flow and architecture, including REST APIs and data engineering architecture, plus analytics thinking and clear communication.
The process includes initial screening, technical interviews, stakeholder discussions, and case work, with final conversations near the end. Candidate reports indicate feedback is typically provided within a week, but offer rate in the dataset is 0.0%, so the data you have here is about what is asked, not how frequently offers are made.
SQL, PySpark, and data flow or architecture show up as top topics across the guides, so you should prepare to connect your SQL and analytics work to end to end data flow and how services expose it, then communicate your reasoning clearly.
