Hi all, I have finished an interview but find the market sizing part quite challenging.
Would appreciate hearing some advice on these questions:
1. What to clarify after an interviewer ask you to do market sizing?
For instance, should I ask whether market sizing is a full case or just a quick market sizing quiz? Is it okay to ask for segmentations first?
2. What is the procedure of a market sizing question?
Is it always stating my structure (or function first), then ask whether interviewer has
related data? Or should I do the calculation based on my assumptions?
3. How detailed should the market sizing be? For instance, the market sizing could be
very detailed (ex: different segment according to age). On the other hand, I can just
list down a math function and allocate my assumption of numbers in it. Does it
depend on how much time the interviewer expects you to complete the market
sizing?
Thanks in advance!
