Summary

Behavioral round at InterSystems for a software engineering role. The twist was that my resume mentioned tutoring a networking course, so they had me actually teach a concept on the spot, which I was not expecting to be that nerve-wracking in an interview setting.

Questions Asked (2)

Q1

Walk me through a networking concept as if you were teaching it to a complete beginner. Use an analogy if it helps.

They pulled this straight from my resume where I listed tutoring a networking course.

Suggested Approach

Choose a fundamental networking concept like TCP/IP or DNS, then explain it using a relatable analogy (e.g., postal system) that maps to the technical components. Keep the explanation simple, avoid jargon, and check for understanding by inviting questions. Relate it back to how this concept impacts software engineering at InterSystems, such as reliability or performance.

Pro tip: Use an analogy that you can extend throughout the explanation, and explicitly state where the analogy breaks down—this shows you understand the concept deeply and can communicate its limitations.

1. Select a Core Concept

Pick a networking concept that is fundamental and relevant to the role, such as TCP/IP, DNS, or HTTP. Ensure it's something you can explain clearly and connect to real-world software engineering.

2. Choose a Relatable Analogy

Select an everyday analogy that maps well to the concept's components and processes. For example, the postal system for TCP/IP, or a phone book for DNS.

3. Explain Step-by-Step

Walk through the concept using the analogy, breaking it into simple steps. Define technical terms as you go, and avoid assuming prior knowledge.

4. Connect to Software Engineering

Relate the concept to practical software engineering scenarios, such as how it affects application performance, reliability, or debugging. Mention its relevance to InterSystems' products if possible.

5. Acknowledge Limitations and Invite Questions

Point out where the analogy falls short to show depth of understanding. Then, ask if the explanation was clear or if they'd like more detail, demonstrating adaptability.

Key Points to Mention

  • Definition of the chosen networking concept in simple terms
  • Clear mapping between analogy components and technical elements
  • Real-world impact on software engineering (e.g., latency, reliability, security)
  • Relevance to InterSystems (e.g., high-performance data platforms, interoperability)
  • Limitations of the analogy to show nuanced understanding
  • Importance of clear communication in technical roles

Suggested Approach

Use the STAR method to describe a specific technical disagreement, focusing on how you separated the problem from the person and used data or prototypes to reach a resolution. Emphasize the positive outcome and what you learned about collaboration.

Pro tip: Show that you can disagree without being disagreeable: acknowledge the teammate's perspective, then explain how you validated the best solution objectively. Interviewers at InterSystems value engineers who prioritize the product over being right.

1. Set the context

Briefly describe the project, your role, and the teammate involved. Keep it concise so you can focus on the conflict and resolution.

2. Explain the disagreement

State the technical disagreement clearly, including both your position and your teammate's position. Avoid blaming language; focus on the issue.

3. Describe your approach to resolution

Explain the steps you took to understand their view, such as asking questions, researching, or proposing a small experiment. Highlight collaboration and data-driven decision making.

4. Share the outcome

Describe the resolution and its impact on the project. If you compromised or adopted their idea, say so and explain why it was the right call.

5. Reflect on the learning

Summarize what you learned about working with others and how you've applied that lesson since. Keep it brief and forward-looking.

Key Points to Mention

  • Specific technical disagreement (e.g., architecture choice, algorithm, testing strategy)
  • Active listening and empathy for the teammate's perspective
  • Use of objective criteria (data, benchmarks, prototypes) to evaluate options
  • Willingness to compromise or change your mind when presented with better evidence
  • Positive outcome for the project and team relationship
  • Lesson learned about communication or collaboration that you've applied since
