Interview Experience: Front End Developer @ JLL (Chhatrapati Sambhajinagar)

I recently went through the interview process for a Front End Developer role at JLL. This was a hands-on, React-focused interview with real-world tasks like API integration, pagination, and building filterable tables. Sharing my experience in case it helps others preparing for frontend interviews.

Getting Started

I got a referral for the position and was contacted by HR shortly after. As part of the preparation, I was asked to set up a local React environment before the interview. This made it clear from the beginning that the process would be practical and coding-heavy rather than purely theoretical.

Round 1: API Integration and Pagination

In the first round, I was given an API and asked to:

• Fetch data from the API
• Display it in the UI
• Implement pagination

I completed the task end-to-end, including data fetching and pagination logic. The UI was functioning as expected, but there was a small intermittent issue where pagination was not syncing properly.

Instead of ignoring it, I clearly explained:

• What the issue was
• Possible causes of the bug
• How I would debug and fix it

I walked the interviewer through my code and reasoning, which helped demonstrate my thought process.

Result: Selected for the next round.

Round 2: Table with Filters

The second round had two panelists and was more focused on UI building and state management.

I was given a hardcoded dataset and asked to:

• Build a data table using any library of my choice

• Add filters for multiple columns using:

  • Text input
  • Date input
  • Dropdown select

I approached this by first building the UI structure and then integrating the data.

What I implemented:

• Table UI with structured data rendering
• Integration of mock dataset
• Filter components for different input types
• State management for applying filters

I was able to complete around 90% of the implementation. The remaining 10% involved finalizing filter logic and edge cases, but I ran out of time.

After the coding part, the discussion shifted to theory:

• How I would complete the remaining logic
• Questions on React fundamentals
• Performance optimizations and best practices

Result: Selected again.

Final Stage

After clearing both technical rounds, HR informed me about a final in-person techno-managerial round. However, there was a delay due to internal townhall meetings.

• I was asked to wait for further updates
• A week passed without communication
• Follow-ups initially didn’t receive a response

Eventually, through my reference, I found out that the position had been closed because they needed someone who could join immediately and had moved forward with another candidate.

Takeaways

• Explaining your thought process clearly can matter more than writing perfect code
• Real-world tasks like API handling, pagination, and filters are common in frontend interviews
• Time management is critical, especially when tasks are UI-heavy
• Hiring decisions can depend on urgency and availability, not just interview performance

Final Thoughts

Even though I didn’t get the offer, the experience was valuable and closely reflected real-world frontend work. It reinforced the importance of communication, structured thinking, and handling practical problems under time constraints.

If you’re preparing for frontend interviews, especially in React, focus on:

• API integration and loading/error states
• Pagination and data handling
• Building reusable UI components
• Implementing filters and managing state effectively
• Debugging real-world UI issues

Practicing projects like tables, dashboards, and filterable lists can significantly improve your readiness for such interviews.
