Costar Research Scientist interview questions & guide 2026

While the title suggests a laboratory or technical data science environment, this position is actually a highly active, communication-driven market research role. You will act as an investigative reporter for the commercial property market, utilizing phone outreach, relationship-building, and public records research to extract proprietary data. It is an excellent launchpad for individuals looking to build a deep, foundational understanding of commercial real estate markets, property valuations, and corporate communication.

The questions you will face during the CoStar hiring process are designed to evaluate your communication clarity, resilience, phone presence, and interest in the commercial real estate sector. These questions are representative of real reported interview experiences and are grouped below by core category to help you identify key patterns.

Motivation and Industry Alignment

These questions assess your understanding of the Research Scientist role, your interest in commercial real estate, and your motivation for joining CoStar.

• Why do you want to work at CoStar, and what do you know about our platform?
• What interests you about the commercial real estate industry?

To succeed in the CoStar interview process, you must shift your mindset toward professional communication, data integrity, and performance resilience.

Verbal Communication & Persuasion – Interviewers will closely evaluate how you project your voice, structure your thoughts on the fly, and handle objections. You must demonstrate that you can guide a conversation professionally and extract key pieces of information without sounding scripted. Practice speaking clearly, maintaining a moderate pace, and expressing polite persistence.

Resilience & KPI Drive – CoStar research operations are highly metric-driven. You must show that you are comfortable with high-volume outreach targets, daily call quotas, and performance tracking. Frame your past experiences around meeting or exceeding structured goals, managing repetitive workflows, and staying motivated through rejection.

Commercial Real Estate Curiosity – While deep industry experience is not always required, a genuine curiosity about how commercial properties are bought, sold, leased, and managed is highly valued. Familiarize yourself with basic terms like occupancy rates, square footage, asset classes (office, retail, industrial, multifamily), and the general business model of CoStar.

The interview process for the Research Scientist position at CoStar is structured to evaluate your practical communication skills and alignment with their high-volume research environment. The process typically moves quickly, often wrapping up within a couple of weeks from the initial application.

The journey begins with a brief recruiter phone screen to discuss your background, location preferences, and basic alignment with the role's requirements. If you pass this stage, you will move to a virtual interview (often via Microsoft Teams) focused on your motivation, interest in commercial real estate, and your comfort level with target-driven environments.

The final stage is an in-person assessment, which frequently takes place at major regional hubs such as Richmond, VA, or London, UK. This onsite stage is comprehensive and typically lasts between two and three hours. It generally includes a presentation about CoStar, a mock phone call simulation, and consecutive interviews with a research manager and a director.

The timeline above outlines the typical progression from your initial application to the final decision. Candidates should use this visual roadmap to pace their preparation, ensuring they dedicate sufficient time to practicing mock phone calls before the onsite assessment. Note that while the steps are standardized, the exact scheduling and group dynamics can vary slightly based on the hiring needs of regional offices.

Telephonic Research & Mock Calls

The mock call is the most critical component of the CoStar onsite assessment. Interviewers use this exercise to simulate your day-to-day responsibilities and evaluate how you perform under pressure.

Be ready to go over:

• Active Listening – Capturing key details mentioned by the contact during a fast-paced conversation.
• Objection Handling – Confidently navigating pushback, such as "I don't have time" or "Why do you need this information?"

As a Research Scientist at CoStar, your primary responsibility is to proactively build, update, and refine the company's proprietary commercial real estate database. This is accomplished through continuous, high-volume outbound telephone research and digital verification.

On a daily basis, you will conduct outbound calls to commercial real estate brokers, property managers, owners, and developers. Your objective during these conversations is to verify real estate transactions, confirm active listings, track tenant movements, and document property details such as square footage, rental rates, and historical sales.

In addition to phone research, you will analyze public records, news sources, and industry listings to identify new construction projects and property sales. You will collaborate closely with regional research teams and managers to ensure that all data entered into the CoStar platform meets strict internal quality and accuracy standards. Your daily productivity will be guided by key performance indicators (KPIs) focused on call volume, database update accuracy, and research coverage.

A successful candidate for the Research Scientist role must combine exceptional verbal communication skills with a methodical approach to data collection.

Q: Is this a technical data science or programming role? A: No. Despite the "Scientist" title, this is a telephonic market research, data verification, and customer outreach role. You will not write code, build machine learning models, or perform advanced statistical programming.

Because research teams work toward collective database coverage, performance metrics and call volumes are often displayed on screens throughout the office floor to foster a transparent, target-driven atmosphere.

They highly value candidates with strong communication skills, coachability, and a positive attitude, regardless of prior real estate experience.

• Prepare for the Mock Call: Treat the mock call during the interview as a real professional interaction. Focus on gathering the requested information, remaining polite under pressure, and showing that you can guide a conversation naturally rather than reading a rigid script.
• Confirm Your Interview Location:

• Showcase Your Drive for Metrics: Frame your past experiences—whether academic, athletic, or professional—around hitting specific goals. Interviewers want to see that you are motivated, rather than intimidated, by daily performance targets.
• Clarify Your Location Preferences: If you are interviewing for a role that has multiple regional hubs, clearly communicate your relocation readiness or local commuting plans. Ensure there is no ambiguity about your commitment to the specific office location to which you applied.
