Summary

PM interview at Meta with a strategy question about acquisitions. Short and punchy but deceptively hard to answer well if you haven't actually thought about it before.

I went with Instagram, which is probably what half the candidates say.

Suggested Approach

Choose one acquisition and build a structured argument around strategic fit, product impact, and long-term value to Meta. Use a framework to compare alternatives briefly, then deep-dive into your chosen acquisition with metrics and user impact.

Pro tip: Acknowledge that 'best' depends on criteria (e.g., revenue, strategic defense, user growth) and state your criteria upfront; this shows product maturity and avoids a subjective debate.

1. Define evaluation criteria

State the criteria you'll use to judge 'best' (e.g., strategic value, revenue impact, user growth, competitive defense, integration success). This sets a clear lens for your answer.

2. Briefly compare top candidates

Mention 2-3 major acquisitions (e.g., Instagram, WhatsApp, Oculus) and quickly assess them against your criteria to show you've considered alternatives.

3. Select and justify your choice

Pick one acquisition (e.g., Instagram) and explain why it best meets your criteria, using specific data and strategic reasoning.

4. Analyze product and strategic impact

Detail how the acquisition strengthened Meta's position: user growth, engagement, monetization, competitive moat, and integration with Meta's ecosystem.

5. Conclude with key takeaway

Summarize why this acquisition was the best and what it teaches about Meta's product strategy and M&A approach.

Key Points to Mention

  • Instagram: $1B acquisition in 2012, now contributes ~$20B+ annual revenue and 2B+ MAU.
  • WhatsApp: $19B acquisition, massive global reach but monetization challenges.
  • Oculus: $2B acquisition, positioned Meta for VR/AR and metaverse, but long-term bet.
  • Strategic rationale: Instagram neutralized a rising competitor and became core to Meta's ad business.
  • Integration success: Instagram maintained brand identity while leveraging Meta's infrastructure and ad platform.
  • User growth and engagement: Instagram's growth outpaced Facebook's, especially among younger demographics.
