OM1 is a healthcare technology company specializing in real-world data and artificial intelligence to improve patient outcomes and healthcare decision-making. The company aggregates and analyzes large-scale clinical data to deliver insights for life sciences, providers, and payers, focusing on enhancing research, treatment effectiveness, and value-based care. As a Data Analyst at OM1, you will contribute to transforming complex healthcare data into actionable intelligence that supports the company’s mission of advancing precision medicine and better patient care.

As a Data Analyst at OM1, you will be responsible for collecting, cleaning, and analyzing healthcare data to generate actionable insights that support clinical research and outcomes measurement. Working closely with data science, engineering, and product teams, you will design and develop reports, visualizations, and data models that inform decision-making for both internal stakeholders and external clients. Typical tasks include identifying data trends, validating data quality, and assisting in the interpretation of complex healthcare datasets. This role is integral to OM1’s mission of improving healthcare outcomes through advanced analytics and real-world evidence.

2.1 Stage 1: Application & Resume Review

The process begins with a detailed review of your application and resume by the Om1 talent acquisition team. At this stage, evaluators look for evidence of technical proficiency in SQL and Python, hands-on experience with data cleaning and transformation, familiarity with building dashboards and reports, and a track record of translating complex data into actionable business insights. Highlighting experience in data pipeline design, stakeholder communication, and problem-solving within large, messy datasets will strengthen your candidacy. Preparing a resume that succinctly captures your impact on business outcomes and your ability to work with both technical and non-technical collaborators is key.

2.2 Stage 2: Recruiter Screen

This step typically involves a 30-minute phone call with a recruiter who assesses your general fit for Om1 and the Data Analyst role. Expect to discuss your career trajectory, motivation for joining Om1, and high-level technical background. The recruiter may probe your communication style and your ability to explain technical concepts to non-expert audiences. To prepare, be ready to articulate your experience with data analytics tools, your approach to stakeholder engagement, and how your skills align with Om1’s mission in healthcare data.

2.3 Stage 3: Technical/Case/Skills Round

In this round, you’ll engage with a data team member or analytics manager in a technical interview that can include SQL or Python exercises, case studies, and scenario-based problem solving. You may be asked to design a data pipeline, clean and organize a large dataset, or perform an analysis to drive business decisions (e.g., evaluating the impact of a product promotion or segmenting users for a campaign). Demonstrating your ability to structure ambiguous problems, write efficient queries, and visualize data for various audiences is crucial. Practicing with real-world datasets and preparing to discuss the rationale behind your analytical choices will help you stand out.

2.4 Stage 4: Behavioral Interview

This stage is often conducted by a hiring manager or cross-functional partner. It focuses on your interpersonal and communication skills, adaptability, and how you handle project challenges. Expect questions about past experiences dealing with data quality issues, collaborating with stakeholders, resolving misaligned expectations, and presenting insights to non-technical audiences. Success here relies on providing concise, impact-oriented stories that showcase your problem-solving, teamwork, and ability to drive projects to completion despite obstacles.

2.5 Stage 5: Final/Onsite Round

The final stage may be a virtual or onsite interview loop involving multiple team members, including senior analysts, data engineers, and product or business stakeholders. You’ll likely participate in a mix of technical deep-dives, case presentations, and collaborative exercises that simulate real Om1 projects. You may be asked to walk through a data project end-to-end, design a reporting pipeline under constraints, or demonstrate how you would make data accessible to a non-technical audience. This is also an opportunity for Om1 to assess your cultural fit and your ability to contribute to a dynamic, mission-driven environment.

2.6 Stage 6: Offer & Negotiation

If you successfully complete the previous rounds, you’ll receive an offer from the Om1 recruiting team. This stage includes discussions about compensation, benefits, and start date, and may involve negotiations with HR or the hiring manager. Being prepared with market data and a clear understanding of your priorities will help you navigate this stage confidently.
