Can you estimate the number of orders Shopee Philippines might process on a day like 11.11, and walk me through your reasoning?

Why This Is Asked
Shopee GDP trainees need to make data-driven decisions across rotations, so this tests structured problem-solving under pressure.
General Approach
Clarify the question, segment the problem, state assumptions clearly, calculate step by step, and sanity-check the result. Practice market sizing cases before the interview.
General Answer
First, clarify what's being estimated: total orders placed in a single 24-hour period on the sale date, as opposed to gross merchandise value or the whole sale week. Then build the estimate from a reasonable top-down base: an approximate online-shopper population in the Philippines, multiplied by an assumed percentage who are active Shopee users, multiplied by an estimated average number of orders each places on a major sale day (typically several times their normal daily rate due to flash deals and vouchers). State every assumption out loud as you go, since the interviewer is grading your reasoning process, not the final number. Cross-check the result against general knowledge of e-commerce scale in the region to see if it feels plausible, and adjust an assumption if the number seems off by an order of magnitude. Close by naming the two or three assumptions your estimate is most sensitive to.
PH Interview Gotcha
Some candidates might freeze or say 'I don't know' without attempting a structure. In the Philippines, there's a tendency to avoid making bold assumptions in fear of being wrong, but interviewers value a logical approach over a precise number.
Sample STAR Answer▾
S
Situation
During the graduate development program interview, the interviewer asked me to estimate daily orders during a mega sale to test my logical thinking.
T
Task
I needed to break down the problem, make reasonable assumptions, and compute an estimate on the spot.
A
Action
I began by clarifying if they wanted orders for just Shopee Philippines or across SEA. They said Philippines. I segmented the market: total internet users in PH, e-commerce penetration, Shopee's market share, average orders per user during a sale. I assumed 70M internet users, 50% use e-commerce, 35M potential online shoppers. During a mega sale, I estimated 20% would place an order, so 7M shoppers. If average orders per shopper is 1.5, that's 10.5M orders. I cross-checked with a top-down approach: total retail market, online share, etc. My final estimate was around 10 million orders.
R
Result
The interviewer seemed satisfied with my structured approach and did not challenge my assumptions heavily. It demonstrated my comfort with ambiguity and quantitative reasoning.
Key Takeaway
I learned to clarify scope first, use both bottom-up and top-down checks, and communicate assumptions clearly.
