Project Deep-Dive (Software Engineer — Phone Screen)
Prepare a structured deep-dive on one significant project you led or owned. In 8–10 minutes, cover the following:
-
Why did you build it?
-
Problem statement, users/stakeholders, business context, and constraints.
-
Main technical challenges
-
Architecture, data/modeling issues (if any), scaling, reliability, integration.
-
Metrics you tracked
-
Goals, success metrics (leading/lagging), SLOs/SLA, guardrails, and how measured.
-
Key trade-offs
-
Alternatives considered and rationale (e.g., build vs. buy, latency vs. freshness).
-
What you would improve if rebuilding
-
Technical debt, design changes, tools/process improvements.
-
Leadership and prioritization
-
Your role, how you aligned stakeholders, set priorities, made decisions, and executed.
