II. Typical Interview Flow and Question Categories (for AI Agent Design)
The SDE 1 (iOS) R1 interview is primarily a Machine Coding / Pair Programming round, supplemented by focused technical and behavioral questions. The AI Agent must be capable of presenting coding challenges, observing/analyzing live code (or a simulated environment), and dynamically probing based on coding choices and errors.
A. Interview Flow Stages:
- Interviewer Introduction & Setup (2-3 mins):
- AI introduces itself, Meesho, and the iOS team's mission.
- Explains the interview format: Machine Coding Round (e.g., 60-75 mins coding, 10-15 mins discussion), screen sharing, strict no-AI-tools policy (must be emphasized by AI).
- Confirms environment setup (e.g., disabling code completion).
- Candidate Self-Introduction (2-3 mins):
- "Why don't you start by introducing yourself?" (Standard opening).
- Coding Problem Statement Presentation & Clarification (5-10 mins):
- AI presents a well-defined iOS coding challenge (e.g., build a screen with dynamic elements like cart functionality, a logo guessing game UI).
- AI prompts for candidate's initial approach/design.
- Dynamic Clarification: AI asks clarifying questions about UI requirements, data modeling choices, edge cases (e.g., "If quantity becomes zero, does the item disappear?"), and preferred UI framework (UIKit/SwiftUI).
- Live Coding / Implementation (45-75 mins - CORE STAGE):
- AI observes the candidate's coding process (requires integration with a live coding environment or simulated environment analysis).
- Dynamic Probing during Coding: AI can ask questions based on observed code:
- "Why did you choose this UI layout (e.g., StackView vs. normal view)?"
- "How are you structuring your data model?"
- "Can you explain the code you're writing for X functionality?"
- Live Debugging Assessment: AI prompts candidate to run code. If errors occur (crashes, UI issues), AI observes and assesses debugging approach.
- "It seems the code isn't running / is crashing. Can you identify and fix the issue?" (AI should watch for systematic debugging steps, e.g., using breakpoints, checking console logs, reviewing configurations).
- Time Management Nudges: AI provides time warnings: "You have about [X] minutes remaining."
- Assess: Functional Correctness, Code Modularity, Productivity/Tools, Speed of Execution, Debugging Proficiency.
- Post-Coding Discussion & Project Deep Dive (5-10 mins):
- AI asks follow-up questions about the completed or partially completed code/design choices.
- "Can you walk me through your implementation process/logic for [specific feature]?"
- "What were the challenges you faced, and how did you address them?"
- "If you had more time, what improvements would you make?"
- Motivation & Fit (2-3 mins):
- "Why are you looking for a change to Meesho now?" / "Why are you specifically interested in Meesho?" (Probes for alignment with Meesho's mission, scale, fast-paced environment).
- Candidate Questions for Interviewer (2-3 mins):
- "Do you have any questions for me?" (AI should be prepared to answer common questions about company culture, work schedule, team, next steps, or provide links to relevant info).
- Interview Conclusion & Next Steps (1 min):
- AI thanks the candidate and informs them that HR will follow up with next steps and feedback.
