1. What is a Data Analyst at Berkeley Research Group?

As a Data Analyst at Berkeley Research Group, you are stepping into a highly rigorous, fast-paced economic consulting environment. This role is foundational to the firm's ability to deliver expert testimony, litigation support, and strategic advisory services. You will act as the bridge between raw, unstructured information and the polished, defensible insights that senior experts and clients rely on to make high-stakes decisions.

Your impact in this position is immediate and highly visible. You will be tasked with processing massive datasets, constructing complex financial or economic models, and ensuring absolute data integrity. Because the work at Berkeley Research Group often ends up in courtrooms, regulatory filings, or boardrooms, the level of accuracy and critical thinking required here goes far beyond a typical industry analytics role.

Expect a role that challenges both your technical acumen and your consulting mindset. You will work closely with senior economists, managing directors, and external legal teams. The problem spaces you tackle will be diverse—ranging from healthcare analytics to antitrust disputes—meaning you will constantly need to adapt to new industries, learn new domain-specific nuances, and present your findings with unwavering confidence and clarity.

2. Getting Ready for Your Interviews

Preparation for this role requires a balance of technical sharpening and behavioral readiness. You should approach your interview as a simulation of the actual consulting environment.

Analytical Rigor and Accuracy – In economic consulting, a single calculation error can compromise an entire case. Interviewers will evaluate your attention to detail, how you QA your own work, and your ability to spot anomalies in complex datasets. You can demonstrate strength here by clearly articulating your data validation processes and emphasizing your commitment to precision over speed.

Technical Proficiency – You must prove you can handle the tools of the trade. Interviewers will assess your comfort with data manipulation, statistical analysis, and visualization. Show your strength by confidently discussing your experience with SQL, Python, R, or advanced Excel, and by explaining why you chose a specific tool for a past project.

Consulting Mindset and Communication – Berkeley Research Group needs analysts who can translate dense technical work into clear business or legal narratives. You are evaluated on your professionalism, executive presence, and ability to explain complex concepts to non-technical stakeholders. Demonstrate this by structuring your answers logically and speaking with clarity and confidence.

Composure Under Pressure – The work environment involves tight deadlines, shifting client demands, and busy senior leadership. Interviewers will look for signs that you are adaptable and unflappable. You can prove this by remaining calm during ambiguous case questions and by sharing examples of how you have successfully navigated high-pressure deliverables in the past.

3. Interview Process Overview

The interview process for a Data Analyst at Berkeley Research Group is thorough and designed to test both your hard skills and your professional endurance. The progression typically begins with a recruiter screening, followed by a virtual manager call or behavioral interview. These initial rounds are standard 30- to 60-minute conversations aimed at assessing your background, your interest in economic consulting, and your baseline communication skills.

If you advance, you will face a technical interview and ultimately an in-person "super-day" or extended onsite loop, often hosted at a local office such as Boston or Washington, DC. This final stage is intensive, lasting up to three hours or more. It generally includes back-to-back 30-minute interviews with various senior staff, a short case study or technical assessment, and sometimes a lunch session with junior staff to assess culture fit.

The firm's interviewing philosophy heavily emphasizes professionalism and applied problem-solving. Because consultants and department heads are frequently balancing active cases, you may encounter interviewers who are managing urgent priorities during your session. The process is rigorous, and the timeline from initial screen to offer can sometimes stretch, requiring patience and proactive follow-up on your part.

This visual timeline outlines the typical sequence of interview stages, from the initial recruiter screen through the final in-person super-day. Use this to pace your preparation, ensuring you are ready for conversational behavioral questions early on, while saving your deepest case study and technical prep for the final rounds. Keep in mind that specific stages—such as the inclusion of a lunch interview or the exact length of the onsite loop—may vary slightly depending on the office location and team.

4. Deep Dive into Evaluation Areas

To succeed, you must understand exactly how Berkeley Research Group evaluates candidates across its core competencies.

Behavioral and Consulting Fit

Because this is a client-facing, high-stakes environment, your professional demeanor is scrutinized just as closely as your technical skills. Interviewers want to know if they can put you in front of a senior partner or a client without hesitation. Strong performance here means demonstrating maturity, a strong work ethic, and the ability to handle constructive feedback.

Be ready to go over:

• Handling tight deadlines – Explaining how you prioritize tasks when multiple urgent requests come in simultaneously.
• Attention to detail – Discussing a time you caught a critical error before it reached a stakeholder.
• Working with busy leadership – Demonstrating your ability to "manage up" and communicate concisely with executives who have limited time.
• Navigating ambiguity – Examples of how you proceed when instructions are vague or data is incomplete.

Example questions or scenarios:

• "Tell me about a time you had to explain a complex analytical finding to a non-technical stakeholder."
• "Describe a situation where you found a significant error in your dataset. How did you handle it?"
• "How do you prioritize your work when two senior managers give you conflicting, urgent deadlines?"

Technical Data Manipulation

You will not just be building dashboards; you will be cleaning, merging, and reshaping massive, often messy datasets provided by clients or opposing counsel. Interviewers evaluate your logical approach to data architecture and your fluency in core querying and programming languages. Strong candidates do not just write code; they explain their logic step-by-step.

Be ready to go over:

• Data cleaning and QA – Techniques for identifying duplicates, handling null values, and validating row counts after joins.
• Advanced SQL – Complex joins, window functions, and subqueries used to aggregate financial or operational data.
• Data analysis with Python/R – Using pandas, NumPy, or R data frames to perform statistical summaries.
• Advanced Excel – Pivot tables, VLOOKUP/XLOOKUP, index-match, and writing complex nested formulas.

Example questions or scenarios:

• "Walk me through how you would QA a dataset containing millions of transaction records to ensure there are no duplicates."
• "Explain the difference between a LEFT JOIN and an INNER JOIN, and tell me a scenario where a LEFT JOIN might artificially inflate your row count."
• "How would you handle a dataset where 20% of the critical financial values are missing?"

Applied Case Study and Problem Solving

During the super-day, you will likely face a short case study. This is designed to test how you structure a problem, make assumptions, and apply analytical techniques to a real-world consulting scenario. Interviewers care more about your framework and logical reasoning than whether you arrive at a perfect mathematical answer.

Be ready to go over:

• Structuring the problem – Breaking down a broad business or legal question into measurable data points.
• Hypothesis testing – Formulating a theory about the data and explaining how you would prove or disprove it.
• Market sizing / Estimation – Making logical, data-backed assumptions when exact numbers are unavailable.
• Identifying edge cases – Recognizing outliers or anomalies that could skew the analysis.

Example questions or scenarios:

• "We are working on an antitrust case in the healthcare sector. How would you approach defining the market share of a specific hospital network?"
• "Walk me through the steps you would take to calculate the lost profits of a business that was forced to shut down for three months."
• "Here is a sample dataset of employee timesheets. What metrics would you look at to determine if there was wage theft?"

5. Key Responsibilities

As a Data Analyst at Berkeley Research Group, your day-to-day work revolves around transforming raw data into reliable evidence. You will be responsible for ingesting large, unstructured datasets from clients, cleaning them, and engineering them into structured formats suitable for deep analysis. This often involves writing complex SQL scripts or Python code to merge disparate data sources, followed by rigorous quality assurance checks to ensure absolute accuracy.

You will collaborate heavily with senior consultants, economists, and managing directors. When a senior expert is drafting a report for litigation, you are the engine providing the charts, tables, and statistical summaries that back up their claims. You will frequently be asked to run sensitivity analyses, adjusting variables in your models to see how different legal or economic assumptions impact the final numbers.

Beyond coding and calculating, a significant part of your role involves documentation and communication. You will need to create clear data dictionaries, document your code so that it can be audited by opposing counsel, and present your interim findings to internal teams. You will often manage multiple project streams simultaneously, requiring you to constantly shift gears between different industries and client problems.

8. Frequently Asked Questions

Q: How long does the interview process typically take? The timeline can vary significantly depending on the office and the urgency of hiring. While some candidates complete the process in a few weeks, others experience delays between rounds. Patience is key, as senior staff schedules are heavily dictated by unpredictable client and litigation demands.

Q: What should I expect during the in-person super-day? Expect a rigorous 3- to 4-hour block at the office. You will typically have a welcome session, an office tour, back-to-back 30-minute interviews with managers and department heads, a short case study or technical assessment, and potentially a lunch with junior staff to assess your cultural fit.

Q: Does Berkeley Research Group support a hybrid work schedule? Yes, Berkeley Research Group generally operates on a hybrid schedule. During your onsite interview or office tour, you will likely receive an overview of the specific in-office expectations for your team, which typically involves being in the office a few days a week to foster collaboration.

Q: What if my interviewer seems distracted or overly busy? Consulting is a demanding field, and department heads are often managing active, high-stakes cases. If an interviewer seems distracted or brings a colleague in to conduct the interview, remain professional, confident, and focused. Treat it as a test of your executive presence and ability to maintain composure under sub-optimal conditions.

Q: Do I need a background in economics or law to succeed? While a background in economics, finance, or litigation support is highly beneficial, it is not strictly required. Strong quantitative skills, flawless data manipulation abilities, and a logical problem-solving framework are the most critical factors for success in this role.

9. Other General Tips

• Prioritize Accuracy Over Speed: In economic consulting, a fast but incorrect answer is a liability. During case studies or technical questions, talk through your QA process. Show the interviewer that you double-check your logic and validate your data at every step.

• Prepare for the "Distracted Executive" Test: You may encounter senior interviewers who are checking their phones or seem rushed. Do not let this rattle you. Speak clearly, get straight to the point, and deliver concise, high-impact answers. This mirrors how you will need to communicate with busy partners on the job.
• Think Out Loud During Case Studies: If you are given a short case or estimation problem, do not calculate in silence. The interviewer wants to hear your assumptions. If you need to assume a market size or a growth rate, state it clearly, justify it briefly, and ask if the interviewer agrees before moving forward.

• Ask Consulting-Specific Questions: At the end of your interviews, ask questions that show you understand the business model. Ask about the types of cases the team handles, how analysts collaborate with expert witnesses, or what the QA process looks like for a major deliverable.
