Summary

Interviewed for a software engineer role at Bilt and the technical portion was basically an interrogation into whether you actually wrote the code on your resume or just managed people who did. Come prepared with specifics or you'll get eaten alive.

Questions Asked (1)

Q1

For a project on your resume, walk me through exactly how much of your time went toward writing code versus designing, meeting, or coordinating. Which files or modules did you own, what languages, rough lines of code, and tell me about a specific bug you had to debug.

Suggested Approach

Choose a project where you had clear ownership and can speak to both technical and collaborative aspects. Structure your answer to first give a high-level overview of your role and time allocation, then dive into specific technical details like files owned, languages used, and a bug you debugged. Be honest about time spent on non-coding activities, as interviewers value self-awareness and teamwork.

Pro tip: Quantify your time allocation with rough percentages (e.g., 60% coding, 20% design, 20% meetings) and tie it to project outcomes to show you understand the business impact of your time. Also, when describing the bug, emphasize the debugging process and what you learned, not just the fix.

1. Set the context

Briefly describe the project, your role, and the team size to orient the interviewer. Mention the project's purpose and your overall responsibilities.

2. Break down time allocation

Provide rough percentages of time spent on coding, designing, meetings, and coordination. Explain why the split was that way and how it evolved over the project.

3. Detail technical ownership

List the specific files or modules you owned, the programming languages and frameworks used, and approximate lines of code. Highlight any complex or critical components you were responsible for.

4. Describe a specific bug

Choose a bug that was challenging and relevant to the role. Explain the symptoms, your debugging approach, the root cause, and the fix. Emphasize what you learned and how you prevented similar issues.

5. Reflect on collaboration and impact

Summarize how your time allocation and technical work contributed to the project's success. Mention any cross-functional coordination and how it influenced your coding decisions.

Key Points to Mention

  • Quantified time allocation (e.g., 60% coding, 20% design, 20% meetings)
  • Specific files/modules owned and their purpose
  • Programming languages and frameworks used
  • Approximate lines of code written or maintained
  • A specific bug: symptoms, debugging process, root cause, fix, and lessons learned
  • Collaboration with other teams or stakeholders and its impact on your work
