Fiber roll-out in a city in Malaysia
The prompt
An operator plans to pass 100,000 homes with fiber in a Malaysian city. Passing each home costs MYR 1,500 and connecting each subscriber costs a further MYR 800. It expects 40 percent of homes to subscribe at an ARPU of MYR 120 a month. Operating costs are 30 percent of revenue. What is the simple payback in years, and how does it change if only 25 percent of homes subscribe?
Your interviewer will share data as you ask for it. Ask clarifying questions, state a hypothesis, then lay out your structure out loud before you calculate.
