The Danger Zone: Top Reasons Candidates Fail

Based on our database of Navan interview outcomes, avoid these common traps:

Blaming the other party entirely and not acknowledging their own role.
Implementing policy checks inefficiently, leading to O(n*m) complexity where n is requests and m is policies.
Incorrectly handling time zone conversions or date rollovers.
Using inefficient data structures for aggregation (e.g., repeatedly iterating through a list).

Test Yourself: Real Navan Questions

Three real prompts pulled from our database.

Type · ownership

Tell me about a time you identified a significant technical debt or performance issue in a system you were working on. What steps did you take to address it, and what was the outcome?

Type · Conflict Resolution

Tell me about a time you had a significant disagreement with a colleague or manager. How did you approach the situation, and what was the resolution?

Type · algorithmic

You are given a list of company policies and a user's travel request. Determine if the request violates any policies. Policies can be complex rules (e.g., 'flights must be economy unless total trip cost exceeds $X', 'hotel stays cannot exceed $Y per night').
