Tempus Interview Process
The Tempus AI software engineer interview process is structured and technically demanding, generally spanning around 4 to 6 weeks from first contact to offer. Most candidates report moving through a series of progressive rounds that test both core engineering skills and an ability to think about problems in a healthcare data context.
  • Recruiter Screen: A 30-minute introductory call covering your background, technical stack, and interest in Tempus's mission in precision medicine.
  • Hiring Manager Screen: Usually around 45 minutes, this conversation typically goes deeper into your past projects and how your experience aligns with the specific team you are interviewing for.
  • Technical Phone Screen: A live coding session, usually around 60 minutes, conducted in a shared editor like CoderPad. Expect one LeetCode-style medium problem or a practical data manipulation task, with an emphasis on talking through your reasoning and handling edge cases.
  • Virtual Onsite: A half-day session typically consisting of 4 to 5 rounds, including two coding rounds, a system design round, a behavioral round, and for senior candidates, a domain depth round focused on your area of specialization.
To prepare effectively for each stage, it helps to organize your study across a few distinct areas that Tempus consistently tests:
  • Data Structures & Algorithms (DSA): Practical coding problems focused on data manipulation, arrays, and algorithm implementation.
  • System Design: Designing scalable, reliable architectures with a healthcare and data-heavy context.
  • Domain Depth (Senior+): A specialized round for senior and staff engineers focused on your specific area of expertise.
  • Behavioral: Competency-based questions tied to Tempus values and collaborative problem-solving.
1. Data Structures & Algorithms (DSA)Tempus coding rounds tend to favor practical problems over pure algorithmic puzzles. Candidates report tasks like processing and filtering large arrays of patient data, or implementing functions to calculate metrics from datasets. A strong grasp of arrays and sliding window patterns will serve you well here.The technical phone screen typically features one medium-difficulty problem, with the onsite coding rounds following a similar difficulty range. Interviewers pay close attention to code readability and how clearly you explain your approach, so think out loud and use descriptive variable names.A focused review of the most commonly tested patterns is the most efficient way to prepare. Working through our top 100 DSA questions will cover the core problem types that come up most frequently in this kind of interview. Sorting through problems by topic, including sorting algorithms and two pointers, will help you recognize patterns quickly under pressure.
2. System DesignTempus system design rounds are rarely generic. Instead of being asked to design a social feed, you are more likely to be asked to design a scalable API for real-time clinical decision support or a data pipeline that integrates EHR data. The healthcare framing is intentional, and showing awareness of reliability and data sensitivity will set you apart.Key topics that come up include load balancing, caching fundamentals, and database replication. Brushing up on system design core concepts before your onsite will give you a solid vocabulary for these conversations.For hands-on practice structuring your answers visually, try working through problems in our System Design AI Whiteboard. Pairing that with the conceptual material on High-Level Design will help you feel prepared for the specific scenarios Tempus tends to use.
3. Domain Depth (Senior+)Senior and staff-level candidates typically face an additional round that goes deep into their specific area of expertise. This is not a generic technical screen but a focused conversation, for example a backend specialist might be grilled on distributed systems, while someone interviewing for a genomics-oriented role might discuss bioinformatics pipelines.For roles touching healthcare data, interviewers have asked about standards like HL7 and FHIR, as well as HIPAA-compliant data storage and encryption patterns. You do not need to be a domain expert walking in, but you should be able to speak fluently about the intersection of software engineering and the specific problem space the team works in.If your role involves data-heavy backend work, make sure you are comfortable with networking fundamentals and have a clear mental model of how distributed systems handle scale and failure.
4. BehavioralTempus behavioral questions are tied to the company's values and tend to focus on collaborative problem-solving and how you handle ambiguity or technical disagreement. Most candidates report structured competency questions like describing a time you pivoted a project due to shifting requirements.Structuring your answers using the STAR principle is the most reliable way to give clear, compelling responses. Preparing 4 to 5 strong stories that you can adapt to different questions will cover most of what you will face.For deeper preparation, the Behavioral Interview Course walks through common question types and how to frame your experiences effectively. The Behavioral Playbook is also a useful reference for quickly reviewing what interviewers are actually looking for in your answers.
ConclusionTempus rewards engineers who write clean, readable code and can connect their technical decisions to real-world outcomes in healthcare. Going in with a genuine curiosity about the mission, alongside solid preparation in DSA, system design, and behavioral storytelling, puts you in a strong position. Follow the Tempus Interview Roadmap for a structured, step-by-step plan covering every stage of the process.
