🧪 Round 1: App Development, Coding Standards, React.js

🧑‍💻 Front-End/React-Focused Questions

Coding/Practical:

1. Build a reusable table component in React that can accept any dataset and allow sorting and filtering.

2. Given a UI mockup, implement a form with validation and real-time error feedback using React.

3. Build a dashboard with tabs showing data from different endpoints (e.g., user stats, activity logs).

4. How would you structure a large React project to ensure maintainability?

Theory/Best Practices:

1. What’s your process for making sure your code follows coding standards?

2. How do you handle state management in medium/large React apps?

3. How do you ensure your app is accessible and responsive?

4. What are the benefits and trade-offs of using React over Power Pages for web development?

🔍 Round 2: Problem Solving, Backend, System Design, SQL, Analytical Thinking

🧑‍💻 DSA/Backend/System-Focused Questions

DSA Coding:

1. Given a list of events with timestamps, group them by user session (e.g., 30 minutes of inactivity breaks a session).

2. Implement a function to detect cycles in a directed graph (think: dependency tracking).

3. Given a list of user activities, return the top 5 most engaged users over a time period.

SQL/Kusto:

1. Write a SQL query to:

   • Find users who haven't logged in for 30 days.

   • List the top 3 communities by engagement last month.

2. Optimize a query with multiple joins and GROUP BY—how would you improve performance?

3. Given a dataset in Kusto, filter logs with error codes above a threshold and group by service name.

System Design:

1. Design a portal for community engagement tracking that supports:

   • Role-based access

   • Real-time updates

   • Metrics dashboard

2. How would you design a Power Pages backend that supports both external users and internal moderators?

Analytical Thinking:

1. A feature rollout caused page loads to spike. How would you diagnose the root cause?

2. If user drop-off is increasing at the sign-up stage, how would you investigate and fix the issue?

⚙️ Round 3: Power Pages and Design Thinking

🧑‍💻 Low-code and UX-centric Questions

Power Pages:

1. Walk me through how you’d create a secure customer feedback portal using Power Pages and Dataverse.

2. How do you integrate Power Automate into a Power Pages workflow?

3. What’s your process for handling authentication and user roles in Power Pages?

Design Thinking:

1. Describe a time when you used design thinking to improve a product feature.

2. How would you go about gathering user feedback and turning it into actionable development work?

3. You’re given a vague requirement like “Improve community engagement.” How would you define the problem and ideate solutions?

4. How do you balance technical feasibility, business requirements, and user needs?
