Why This Is Asked
BCG evaluates your ability to decompose a vague market-sizing problem, make reasonable assumptions, and link the estimate to a practical business strategy. This mirrors the real casework where consultants need to size opportunities under uncertainty.
General Approach
Use a structured framework such as population-based bottom-up or household-based top-down. State your assumptions clearly, show your math, then pivot to a specific, data-supported recommendation that addresses a distinct competitive gap.
General Answer
Follow the two-part structure the question asks for. For the sizing: state the framework first, either a household-based top-down approach (estimate Metro Manila households, apply an assumed penetration rate for food-delivery app usage, multiply by an assumed average order value and monthly order frequency, then annualize) or a population-based bottom-up approach (estimate the addressable urban population, an assumed share who order delivery regularly, average spend per order, and order frequency). State each input explicitly as an assumption, show the multiplication clearly, and sanity-check the resulting figure against what seems plausible for a market this size, rather than presenting invented numbers as verified data. For the growth strategy: since a local challenger cannot out-spend a well-funded global player like GrabFood on subsidies or rider supply, the recommendation should target a distinct competitive gap rather than copy GrabFood's playbook at a smaller scale. Reasonable, defensible angles include a lower commission structure to win over merchants who feel squeezed by aggregator fees, a hyper-local focus on underserved areas or cuisines that larger platforms deprioritize, deeper support for cash-based payment given that a meaningful share of Filipino consumers remain unbanked or cash-preferring, or distribution through existing community channels rather than building parallel logistics from scratch. The strongest answers pick one specific angle and explain the mechanism by which it creates a defensible advantage, rather than listing several generic ideas.
PH Interview Gotcha
Don't say 'I will assume 50% market share' without justification. Instead, use a logical bottom-up or top-down approach based on real Philippines demographics. Practice saying 'I will start by creating a framework before doing the math.'
Sample STAR Answer▾
S
Situation
I was leading a team project for a local online food-delivery startup that wanted to raise Series A funding by demonstrating a solid understanding of the Metro Manila market.
T
Task
I needed to estimate the total addressable market and propose a specific, data-backed growth strategy that would differentiate the startup from larger competitors.
A
Action
I built a bottom-up model starting with Metro Manila's population (about 14 million), estimated the percentage of working-age adults who order food online (30%), their average order frequency (twice a week), and average order value (PHP 250). That gave me an annual market size of roughly PHP 54 billion. I then analyzed competitor gaps and identified that office lunch deliveries during peak hours were underserved. I proposed partnering with 20 major BPO hubs to offer exclusive lunch bundles and guaranteed 30-minute delivery, which required negotiating with commissaries and hiring additional riders for the lunch shift only.
R
Result
The startup used the market-sizing estimate and strategy in their pitch deck and successfully secured PHP 15 million in seed funding within three months. The lunch-bundle pilot in three BPO hubs increased repeat orders by 40% within the first quarter.
Key Takeaway
Ground your market-size assumptions in local data and regulatory constraints.
