The 011h DNA (TL;DR)
011h's 'Construction, reassembled.' ethos drives the interview loop, grading for candidates who can innovate within industrial contexts. They seek individuals who demonstrate the ability to scale solutions, optimize 'Capacidad productiva con alcance nacional', and integrate new technologies effectively into existing workflows.
The 011h Interview Loop
Your onsite loop will typically consist of 5 rounds.
- 1
Round 1
Recruiter ScreenMotivation, role fit, logistics. - 2
Round 2
Coding ScreenLeetCode-medium algorithmic problems under time pressure. - 3
Round 3
System DesignDistributed systems, trade-offs at scale, architecture under constraints. - 4
Round 4
Onsite CodingLeetCode-hard problems, reasoning about defects, code clarity, edge cases. - 5
Round 5
Behavioral / LeadershipPast evidence of ownership, influence, resolving conflict.
The Danger Zone: Top Reasons Candidates Fail
Based on our database of 011h interview outcomes, avoid these common traps:
- Not discussing trade-offs between detection latency and accuracy.
- Ignoring the downstream implications of the chosen technical path
- Not considering potential concurrency issues or race conditions in data aggregation.
- Ignoring edge cases like machines with no scheduled maintenance.
Test Yourself: Real 011h Questions
Three real prompts pulled from our database.
Type · Collaboration
At 011h, we often have to balance the high precision requirements of industrial construction with the need for rapid digital deployment. Describe a time you had to reconcile a strict architectural requirement with a teammate who prioritized speed or a different technical approach. How did you ensure the final output maintained our construction quality standards while respecting the project timeline?
Type · Learning
Our platform must integrate with a wide variety of legacy industrial hardware and modern BIM software interfaces. Tell me about a time you had to master a complex, poorly documented industrial protocol or API to enable a critical system integration. How did you validate your understanding of the system before building the production-ready connector?

9 of 13 questions shown
1
Recruiter Screen
1- 1
Type · Motivation
What interests you about working at 011h, specifically within the industrial sector, and how do your career goals align with our mission to optimize industrial operations through software?
2
Coding Screen
3- 2
Type · Algorithmic
Given a stream of sensor readings from an industrial machine, design an algorithm to detect anomalies that indicate potential equipment failure. Assume readings can be noisy and intermittent. - 3
Type · Data Structures
Implement a data structure that efficiently stores and retrieves historical operational data for thousands of industrial assets, supporting queries for data within specific time ranges and filtering by asset ID. - + 1 more questions in this round (sign up to unlock)
3
System Design
3- 4
Type · Architecture
Design a system to ingest, process, and visualize real-time telemetry data from thousands of geographically distributed industrial IoT devices. Consider data volume, latency, reliability, and security. - 5
Type · Scalability
How would you design a system to predict equipment failures based on historical sensor data and maintenance logs? Discuss the data pipeline, model training, and deployment strategy. - + 1 more questions in this round (sign up to unlock)
4
Onsite Coding
3- 6
Type · Debugging
A critical dashboard displaying machine uptime is showing incorrect data. The backend service responsible for aggregating this data seems to be the culprit. Debug this issue, focusing on identifying the root cause and proposing a fix. - 7
Type · Edge Cases
Write a function to calculate the optimal batch size for processing sensor data, considering factors like throughput, latency, and memory constraints. Ensure your function handles edge cases gracefully. - + 1 more questions in this round (sign up to unlock)

Frequently asked questions
How long does the 011h 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 011h?
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 011h?
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.
