How long does the Indra interview process take?

Most candidates spend between 4 and 8 weeks from recruiter screen to offer. The onsite loop itself runs in a single day or is split across two half-days, with debrief and offer typically within 5 business days after.

How should I prepare specifically for Indra?

Focus on three things: (1) the company DNA shown above - what they actually grade for, (2) the rounds in your loop, especially the round most candidates underestimate, and (3) drilling on the question types in this guide using a structured framework like CIRCLES or STAR.

Does this apply to engineering or design roles at Indra?

The DNA stays the same - what changes is the round mix. SWE candidates face coding screens instead of Product Sense; designers face portfolio reviews and design exercises. The "what they value" and behavioral signals carry across all functions.

How to Pass the Indra Software Engineer Interview in 2026

The Indra DNA (TL;DR)

Indra grades for safety-critical engineering discipline - DO-178C compliance for avionics, MITRE ATT&CK literacy for defense systems, and concrete experience with their core platforms (iSpace, MAESTRO air-traffic control). Expect rigorous traceability questions: how you'd document a requirement back to a failed test case, and how you scoped the blast radius of a deployment.

The Indra Interview Loop

Your onsite loop will typically consist of 5 rounds.

1
Round 1
Recruiter Screen
Motivation, role fit, logistics.
2
Round 2
Coding Screen
LeetCode-medium algorithmic problems under time pressure.
3
Round 3
System Design
Distributed systems, trade-offs at scale, architecture under constraints.
4
Round 4
Onsite Coding
LeetCode-hard, debugging, code clarity, edge cases.
5
Round 5
Behavioral / Leadership
Past evidence of ownership, influence, resolving conflict.

The Danger Zone: Top Reasons Candidates Fail

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

Failing to articulate the specific actions taken to solve the problem.
Claiming to learn instantly without mentioning specific methods or resources.
Not addressing the critical requirement for extremely low latency and high reliability.
Handling edge cases like data gaps or erroneous readings.

Test Yourself: Real Indra Questions

Three real prompts pulled from our database.

Type · Conflict Resolution

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

Type · Architecture

How would you design a distributed system to manage air traffic control (ATC) communications for a major airport? Consider reliability, low latency, and the ability to handle peak traffic loads.

Type · Algorithmic

Implement a function to efficiently find the shortest path for an aircraft to travel between two waypoints, avoiding a set of known no-fly zones (NFZs). The flight path can only be composed of straight line segments between predefined navigation points.

10 of 19 questions shown

Recruiter Screen

1
Type · Motivation
Why are you interested in applying your software engineering skills to the aerospace industry, specifically at Indra?
2
Type · Logistics
What are your salary expectations for this role, and what is your availability to start?

Coding Screen

3
Type · Algorithmic
Given a stream of flight data (e.g., aircraft ID, timestamp, position), design an algorithm to detect potential airspace intrusions within a specified safety zone in real-time. Assume the zone is a complex polygon.
4
Type · Algorithmic
You are given a set of radar track data for multiple aircraft. Write a function to determine the closest approach time and distance between any two aircraft in the set, considering their current velocity and heading.

System Design

5
Type · Architecture
Design a scalable system for processing and analyzing telemetry data from a fleet of commercial aircraft. The system needs to ingest data in real-time, store it efficiently, and support complex analytical queries for predictive maintenance.
6
Type · Architecture
How would you design a distributed system to manage air traffic control (ATC) communications for a major airport? Consider reliability, low latency, and the ability to handle peak traffic loads.

Onsite Coding

7
Type · Debugging
A critical component in our air traffic management system is intermittently failing to update aircraft positions. The logs show occasional 'timeout' errors but no clear pattern. Debug this issue.
8
Type · Data Structures
Implement a data structure that can store and efficiently query flight paths, supporting operations like finding all paths that intersect a given geographical region, and retrieving the longest path stored.

Behavioral / Leadership

9
Type · Ownership
Tell me about a time you took ownership of a challenging technical problem that was outside your direct responsibility. What was the situation, what did you do, and what was the result?
10
Type · Conflict Resolution
Tell me about a time you had a significant disagreement with a colleague or manager regarding a technical decision. How did you approach the situation, and what was the resolution?
