Why This Is Asked

BCG wants to assess your ability to use structured, data-driven reasoning to influence without authority. This simulates consultant-stakeholder dynamics where you must win buy-in for fact-based recommendations.

General Approach

Use the PEI format: briefly describe the conflict, your analysis, and your persuasion technique. Emphasize how you tailored the data presentation to the stakeholder's priorities and used a controlled pilot to de-risk the decision.

Sample STAR Answer
S

Situation

I was an insights analyst working with a BPO account director who insisted on renewing a client's contract with the same staffing model, despite rising attrition in that account.

T

Task

I needed to convince the director to shift to a hybrid staffing model (onshore and offshore) using historical attrition and cost data, even though he believed the current model was more 'client-safe.'

A

Action

I prepared a one-page data summary showing that the account's attrition rate was 40% higher than similar accounts, costing the company PHP 2.5 million in rehiring and training over the past year. I then modeled two scenarios: status quo vs. hybrid. The hybrid model predicted a 25% lower attrition rate and 15% cost savings. I scheduled a 15-minute meeting and started by acknowledging his concern about client perception, then walked him through the numbers visually. I offered a pilot for just one team to prove the model before rolling it out broadly.

R

Result

The director agreed to a three-month pilot on two teams. The hybrid model reduced attrition by 30% and saved PHP 300,000 in recruitment costs. He then scaled it to four other accounts within six months.
