Interview Process
The interview process began with a resume screening followed by a detailed questionnaire that included inquiries about my favorite project, top qualities, and competing offers (essentially an HR round). This was followed by two interviews: one technical and one that combined technical and HR elements.
Interview 1:
- Focused on code review and debugging challenges.
- Task involved a Java class implementing a shortest path finder for a navigation system, where I needed to find the nearest path from a source city to a destination with weighted edges.
- The provided code attempted to use Dijkstra’s algorithm but contained mistakes that I was asked to fix.
- Tasks included:
- Analyzing time/space complexity (expected to be O((V+E)logV))
- Identifying and fixing the edge update logic
- Explaining why Dijkstra’s algorithm is suitable for this use case compared to alternatives like A* and Floyd-Warshall.
- The interviewer emphasized debugging the existing algorithm rather than rewriting it from scratch.
- Follow-up question: How would you handle negative edge weights? (Discussed the Bellman-Ford algorithm and its workings.)
Interview 2:
- Conducted an extremely detailed walkthrough of my resume, covering every project, technology choice, and outcome.
- Engaged in a technical project deep-dive, explaining architecture decisions, trade-offs made, and lessons learned.
- Tesla-specific questions included:
- Why Tesla over other tech companies?
- What specific aspect of Tesla’s culture/mission appeals to you?
- How do you handle fast-paced, high-pressure environments?
- Describe a time you had to learn something completely new quickly.
- Behavioral questions included:
- Tell me about a time you disagreed with your manager.
- How do you handle criticism of your work?
- Describe your biggest professional failure.
- I felt unprepared for the behavioral component despite performing strongly in the technical part.
Technical Questions
- Code review and debugging of a Java class for shortest path finding using Dijkstra’s algorithm.
- Analysis of time/space complexity.
- Discussion of handling negative edge weights using Bellman-Ford algorithm.
Tips & Insights
Tesla releases a large number of internship spots, but each spot is for a single team. The most challenging part is making it to a human recruiter. Once you reach that stage, I hope you perform better than I did and secure an offer. Best of luck!
