Product design question

You are the PM for Google Voice. How you improve it?

Practice this question out loud. An AI interviewer asks it, follows up like a real interviewer would, and scores your answer. Type or speak.

What this question tests

Product improvement thinking for a lower-priority, legacy product, finding a realistic value proposition given limited investment.

Clarify the current state, is Google Voice mainly used for a free secondary number, call screening, or SMS forwarding today.
Identify the core remaining use case, likely privacy-conscious users wanting a separate number for calls and texts without a second SIM.
Assess what's broken or dated, likely the interface feels neglected and lacks integration with modern communication habits like group chats.
Propose focused improvements, better spam call filtering using Google's existing AI capabilities and tighter integration with Google Workspace for small business users.
Consider audience, small businesses needing a lightweight virtual phone line could be an underexploited segment worth focusing on.
Define success metrics, active number retention rate and spam call filter accuracy, given limited resources.

Accepts the product's realistic scope, a lower-investment legacy product, and proposes focused rather than sweeping improvements.
Identifies a specific underexploited segment, small businesses, rather than trying to compete broadly with modern messaging apps.
Leverages Google's existing AI and spam detection strengths rather than proposing an expensive rebuild.
Sets a metric appropriate to the product's realistic scope, retention and spam accuracy, not aggressive growth targets.

Proposing an ambitious full rebuild without acknowledging the product's likely limited investment level.
Not identifying a specific underserved use case or segment to focus on.
Ignoring existing Google capabilities, like spam detection, that could be reused cheaply.
