Written feedback for the candidate

What went well?

  • Good clarifications up front. TC used opportunity to increase scope to what they thought they’d like to explore.
  • Good structure allowed interviewer to easily keep track, frequent check-ins throughout interview and signposting ensured things stayed on track.
  • Well defined “memorable” and ambitious vision - and clear optimization towards this throughout the interview.
  • Experience with hardware products came through very clearly, especially when talking about the product design aspect.
  • Risks and mitigations were well done, showed an awareness of the usual implications of home products

Where is the room for improvement?

  • Net sales can be a risky metric to optimize for, TC did a good job in flagging out possible cons and mitigating them with secondary metrics, but would also recommend flagging out (proactively) the lagging nature of revenues as an indicator and also mitigating that through proxies
  • At some sections, TC’s product ideas seemed more driven by “the technology exists, we should use it”, rather than solving an underlying customer need. Got this impression in 2-3 sections, so would recommend hedging against this by always tying solutions / problems / impact back to customers and their pain points.
  • Prioritizing GTM in tying in with Echo/Home vs standalone was slightly unclear at the start although clarified later - seemed a bit like the candidate wanted to achieve both, but then decided standalone is a stronger USP given the hardware aspect.
  • Summarization needs a bit of work, the tie-in to Facebook’s mission was very cleverly done, but it’s important to be able to distill the key takeaways from a session

Can you ask the candidate for feedback about this mock too? Did the candidate find it useful? It's the first time I took a PM mock for a hardware role, so good to benchmark.
