Candidates describe a two-stage Cornerstone Research analyst process: short back-to-back first-round interviews, then an in-person superday. Both stages mix behavioral questions with interviewer-led economics cases.

Process Length
Most candidates describe a first round of two back-to-back interviews, followed by an in-person superday of about four interviews. Session lengths vary by report, from 30 to 45 minutes. Each session typically pairs behavioral questions with a case, and the cases appear to come from real economic consulting work rather than standard management frameworks.
The cases reported span antitrust and monopoly questions, overcharge and damages estimates, IP infringement, a stock-market event, and graph interpretation, such as explaining a downward trend after 2015. Several candidates say interviewers lead the case, feed in information gradually and guide you if you stall. One offer recipient advised treating each case like an economics problem set, asking clarifying questions and reasoning aloud. Another candidate was asked to design an empirical method for evaluating damages and to say which variables to control for.
Behavioral questions are usually direct: why Cornerstone, why economic consulting, and a detailed walk-through of a research or data project from your resume. Be ready to explain your methods and assumptions.
Outcomes in this set are mixed: one candidate reports an offer, and the others report rejections. Some describe the superday as tiring, and a few mention uneven interviewer engagement, so practice staying structured through back-to-back cases.

Real interview reports from people who went through the Cornerstone Research process.
My interview with Cornerstone Research started with a video round that felt surprisingly collaborative. The interviewers were friendly and walked me through case scenarios in a guided format. I was asked standard motivation questions—why the company, why the role—and then moved into case work covering financial and economic topics. One specific case asked me to analyze a downward trend in a graph after 2015 and speculate on what might have caused it. The video round went reasonably well, and I was invited to a superday in their office.
The in-person day consisted of four consecutive back-to-back interview sessions, each about 30 minutes. The cases continued in a similar vein to the video round—real client engagements with details stripped back so I could work through the analysis with the interviewer. They emphasized that staying calm was important, especially as the day wore on and fatigue set in. The team was cooperative overall, and the analysts I spoke with gave the impression they genuinely wanted to help candidates think through problems, even though the cases themselves were moderately challenging. One interviewer was about 20 minutes late, which threw off the rhythm slightly, but the process itself felt well-structured.
The interviews assessed a mix of technical problem-solving, analytical thinking, and behavioral fit. I didn't advance to an offer, but I came away respecting the caliber of the work they do and how seriously they take the case interview format. If I were to try again, I'd spend more time practicing how to stay composed when working through unfamiliar data and economic scenarios under observation.
Prep tip from this candidate
Practice maintaining composure through a full day of consecutive case interviews—Cornerstone runs a marathon format with four back-to-back sessions. Focus on graph interpretation and causal reasoning in financial contexts, and come prepared to think aloud while the interviewer guides you through real client cases.

Synthesized from candidate reports. Individual experiences may vary.
Candidates report applying with a resume and cover letter, or connecting through campus recruiting or a career fair. One candidate heard about a first-round interview about a week after the campus deadline. Timing likely varies by office and recruiting cycle.
Candidates typically describe two consecutive interviews with analysts, reported at 30 or 45 minutes each. They often open with introductions, why Cornerstone and why economic consulting, and a resume project. Most of the time then goes to an interviewer-led case, such as overcharging, antitrust, or interpreting a graph.
Candidates who advance report an in-person superday of about four interviews with analysts, associates, managers or a principal. Some report a purely behavioral round, and the rest mix behavioral questions with cases. Cases may cover antitrust questions or how to empirically estimate damages. Some candidates call the day tiring, and lunch was reported as not evaluated.
Reports of outcomes are mixed. One candidate received an offer after the superday, while others were rejected after the first round or after the superday. One candidate heard back within six days of their interview day, so timing likely varies.
