How do you implement intercepting routes in App Router?
Interviewer Expectations for this Question
01
Core Competency
Assesses fundamental understanding of Next.js conventions, runtime behavior, and memory/performance considerations.
02
Evaluation Criteria
Hiring managers look for precision, avoidance of ambiguous jargon, and ability to explain trade-offs under real production conditions.
Comprehensive Model Answer
Verified Solution
Intercepting routes allow you to load a route from another part of your application while keeping the context of the current page, similar to modals.
app/
├── feed/
│ └── page.js
├── photo/
│ └── [id]/
│ └── page.js
└── @modal/
└── (..)photo/
└── [id]/
└── page.js
The (..) convention indicates that you want to intercept routes at the same level. Intercepting routes use conventions like:
(.)- match segments on the same level(..)- match segments one level above(..)(..)- match segments two levels above(...)- match segments from the root app directory
Candidate Response Strategy & Interview Tips
- Start with a concise one-sentence summary: Deliver a direct, confident answer first before expanding into nuances.
- Demonstrate real-world trade-offs: Discuss where this approach excels and when you would avoid it in production systems.
- Discuss complexity & edge cases: Proactively explain time/space complexity or boundary conditions (null values, scale limits).
- Prepare for interviewer follow-ups: Technical hiring panels frequently probe deeper into concurrency, backward compatibility, or alternative libraries.
