Behavioral Deep Dive: Impactful Project and Mentorship (30–40 Minutes)

Part A — Impactful Project Deep Dive

Walk through one impactful software engineering project. Cover:

1. Problem context and goals

• What was broken or missing? Who were the users/customers? Why now?
• Success criteria and measurable targets.

2. Your role and responsibilities

• Scope of ownership, team size, collaborators, and what you personally delivered.

3. Technical approach and architecture

• High-level system design, data flows, interfaces, and key components.

4. Key decisions and trade-offs

• Alternatives considered, why you chose one, and the risks you accepted.

5. Timeline and constraints

• Milestones, resources, dependencies, compliance/security, performance, SLAs.

6. Metrics of success

• Baselines vs. outcomes (latency, throughput, availability, cost, dev velocity, user adoption).

7. Lessons learned

• What you’d repeat, avoid, or do differently.

Part B — Biggest Challenge

• What was the hardest problem? Why was it difficult?
• How you diagnosed and resolved it.
• Alternatives you weighed and trade-offs.
• Measurable impact of the solution.

Part C — Mentorship Example

Describe a time you mentored a teammate or intern (on this project or elsewhere):

• Goals you set (onboarding, scope, success criteria).
• How you provided guidance (design reviews, pairing, code reviews, unblocking).
• How you measured progress.
• Outcome and what you’d do differently.

Note: Keep proprietary details anonymous. A simple architecture diagram you can explain verbally is encouraged.
