A Research Scientist at RTI International occupies a prestigious and highly impactful role within one of the world’s leading independent, non-profit research institutes. In this position, you do not merely conduct academic exercises; you design and execute rigorous, multi-disciplinary research that directly addresses some of the most pressing global challenges in public health, education, social policy, environmental science, and international development. Your work serves as the scientific foundation upon which governments, commercial entities, and non-profit organizations make critical decisions and policy changes.

The impact of this role is felt globally. Whether you are analyzing large-scale epidemiological datasets for federal clients like the CDC or NIH, evaluating educational programs, or modeling environmental risks, your findings directly influence public policy and human well-being. RTI International prides itself on converting knowledge into practice, meaning your research will actively shape real-world programs and interventions rather than sitting on a shelf.

To succeed as a Research Scientist, you must possess not only exceptional technical and methodological expertise but also the strategic acumen to manage complex client relationships and federal contracts. This dual requirement of scientific excellence and client-facing professionalism makes the role both highly challenging and deeply rewarding. Candidates must enter the interview process prepared to demonstrate how their research background translates into actionable, high-quality deliverables within a collaborative, mission-driven environment.

The interview questions for the Research Scientist position at RTI International are designed to probe your scientific rigor, behavioral resilience, and alignment with the institute's mission. These questions are representative of actual candidate experiences and are structured to highlight patterns in how the hiring teams evaluate talent.

Research Methodology & Domain Expertise

This category evaluates your technical competence, your ability to design sound research studies, and your familiarity with specialized tools and statistical methods.

• Describe your experience with quantitative and qualitative research design, and how you select the appropriate methodology for a new project.
• How do you handle missing or low-quality data when working on a tight project deadline?

Preparing for an interview at RTI International requires a balanced approach that demonstrates both your scientific credentials and your professional adaptability. You should think of the interview process as a holistic evaluation of how you perform as a researcher, a consultant, and a teammate.

Scientific and Methodological Rigor – This is the foundation of your evaluation. Interviewers will closely examine your past publications, projects, and methodologies to ensure your work meets the highest standards of scientific integrity. Be prepared to explain the "why" behind your research decisions, including your choice of statistical models, datasets, and control variables.

Communication & Stakeholder Management – At RTI International, scientists frequently interact with government clients, policymakers, and community stakeholders. You must demonstrate that you can translate complex scientific concepts into clear, actionable insights for non-technical audiences. Your ability to present your ideas with clarity, confidence, and empathy is highly scrutinized.

Mission Alignment & Adaptability – As a non-profit organization dedicated to improving the human condition, RTI International looks for candidates who genuinely align with their core values. You should be ready to discuss how your research contributes to societal well-being and how you handle the shifting priorities and administrative complexities typical of federal contracting.

The interview process for a Research Scientist at RTI International is comprehensive and designed to thoroughly vet your technical capabilities and cultural fit. While the process is highly structured, candidates should be prepared for potential variations in timeline and responsiveness, which can sometimes be influenced by contract funding cycles and administrative processes.

The journey typically begins with an initial screening call with an HR representative to discuss your background, salary expectations, and basic alignment with the role. If you pass this screen, you will progress to a more technical Zoom interview with the hiring manager or a small panel of peers. For candidates who advance past this stage, the final round often consists of a full-day interview panel—either on-site or virtually—where you may be asked to present your past research, participate in multiple one-on-one or group interviews, and meet with key stakeholders from the practice area.

This visual timeline illustrates the typical progression from the initial application to the final offer. Candidates should use this timeline to pace their preparation, ensuring they allocate sufficient time to practice their research presentation before reaching the intensive panel stage. It is important to note that timelines can sometimes stretch over several weeks between stages due to the collaborative and consensus-driven nature of the hiring teams at RTI International.

To excel in the RTI International interview process, you must understand the specific competencies that interviewers are trained to evaluate.

Research Design and Methodology

This area focuses on your ability to conceptualize, structure, and execute scientifically sound research projects. Interviewers want to see that you do not just follow protocols, but that you understand the underlying scientific principles and can innovate when faced with real-world data limitations.

Be ready to go over:

• Experimental and Quasi-Experimental Designs – Understanding how to establish causal relationships in real-world settings where randomized controlled trials may not be feasible.
• Statistical Software and Tools – Your proficiency in programming languages and platforms such as R, SAS, Python, or SPSS to clean, analyze, and visualize data.
• Proposal and Grant Writing – The ability to draft compelling technical sections for proposals to secure funding from federal agencies like the NIH, CDC, or EPA.
• Advanced concepts – Bayesian inference, longitudinal data analysis, mixed-methods research designs, and geospatial analysis.

Example scenarios:

• "Explain how you would design a program evaluation for a public health intervention with no baseline data."
• "Walk us through how you would handle a dataset with a high rate of non-response or missing variables."

Client and Stakeholder Communication

As a Research Scientist, you will often act as the face of RTI International to clients and external partners. This evaluation area measures your ability to build trust, manage expectations, and present data in a compelling, easy-to-digest manner.

Be ready to go over:

• Technical translation – Converting complex statistical outputs into policy briefs, executive summaries, and interactive dashboards.
• Conflict resolution – Navigating situations where a client's political or organizational goals conflict with your objective scientific findings.
• Presentation skills – Delivering engaging, professional presentations to diverse groups, ranging from academic peers to community members.

Example scenarios:

• "How would you deliver disappointing research results to a client who was expecting a highly successful program outcome?"
• "Describe a time you had to present complex scientific data to a community group with no technical background."

Professional Poise & Cultural Alignment

RTI International values collaborative, respectful, and mission-driven professionals. This area evaluates how you handle high-pressure situations, your commitment to diversity, equity, and inclusion, and how you maintain your composure during challenging professional interactions.

Be ready to go over:

• Resilience under pressure – Staying calm and professional when faced with demanding clients or difficult, probing questions from interviewers.
• Diversity, Equity, and Inclusion (DEI) – Articulating how you incorporate diverse perspectives into your research teams and study designs.
• Collaboration – Demonstrating a track record of supporting colleagues and contributing to a positive, inclusive workplace culture.

Example scenarios:

• "How do you respond when an interviewer or colleague aggressively challenges your research assumptions?"
• "What does diversity, equity, and inclusion mean to you in the context of scientific research?"

The day-to-day work of a Research Scientist at RTI International is dynamic, intellectually stimulating, and highly collaborative. You will rarely work in isolation; instead, you will operate as part of multidisciplinary project teams dedicated to solving specific client challenges.
