← instalilyAI Interview Insights
Start with a high-level overview of the app's purpose and constraints, then dive into 2-3 key design decisions, explaining the trade-offs and why you chose that path. Conclude by reflecting on what you learned and how you would iterate.
Pro tip: Frame your decisions as hypotheses validated through rapid prototyping and user feedback, showing you balance technical rigor with business impact. Also, acknowledge any limitations and how you'd address them with more time.
Briefly describe the app's goal, target users, and any constraints (time, data, compute) that shaped your approach.
Select 2-3 critical design choices (e.g., model selection, architecture, data pipeline) and explain the rationale behind each.
For each decision, articulate the alternatives considered and the trade-offs (e.g., accuracy vs. latency, cost vs. scalability).
Describe how you handled ambiguity or changes during development, such as pivoting based on new information or user feedback.
Summarize lessons learned and outline next steps or improvements you would make with more time or resources.
AI-generated suggestions, not part of the candidate's original notes. May be inaccurate — verify before relying on them.
Easier to answer than I expected because I actually knew where my app was weak.
Acknowledge the limitations honestly, framing them as conscious trade-offs made under constraints. Then, for each limitation, propose a concrete improvement, showing you've thought deeply about the system's evolution. Balance technical depth with business impact, and tie your changes to scalability, reliability, or performance gains.
Pro tip: Focus on 2-3 high-impact limitations rather than listing many minor ones; depth over breadth demonstrates senior-level prioritization. Also, mention any monitoring or metrics you'd add to validate the improvements.
Briefly describe the system you built, its purpose, and the constraints (time, resources, scale) that shaped your decisions.
Select 2-3 significant architectural limitations, explaining why they exist and their impact on performance, scalability, or maintainability.
For each limitation, outline a specific change you would make, such as adopting a new technology, refactoring a component, or adding a layer.
Explain how each improvement would enhance the system, using metrics like reduced latency, increased throughput, or lower cost.
Summarize what you learned from the experience and how it would influence your future architectural decisions.

Awkward question to get in a live demo setting.
Acknowledge that not finishing everything is normal in fast-paced AI development, then focus on how you prioritized, communicated, and delivered value. Show that you made deliberate trade-offs, kept stakeholders informed, and set up a clear path for the unfinished work.
Pro tip: Frame unfinished work as a strategic decision, not a failure—explain what you learned from shipping the core and how that informed the roadmap for the rest. This shows product thinking and ownership.
Briefly describe the project, your role, and the constraint (e.g., tight deadline, shifting requirements) that led to unfinished parts.
Detail how you decided what to build first—e.g., focusing on core user value, technical dependencies, or MVP scope—and what you consciously deferred.
Explain how you kept stakeholders informed, managed expectations, and any interim solutions (e.g., feature flags, manual workarounds) you put in place.
Highlight what was delivered successfully, the impact, and what you learned that improved future planning or execution.
Describe how you handed off or scheduled the remaining work, ensuring it wasn't forgotten and had a clear owner and timeline.
