How to Pass the BP Software Engineer Interview in 2026
The BP DNA (TL;DR)
BP values safety, sustainability, and operational excellence. They seek candidates demonstrating problem-solving, adaptability to global energy challenges, and strong collaboration within a structured, process-driven environment, emphasizing long-term impact and ethical conduct.
The BP 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, debugging, 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 BP interview outcomes, avoid these common traps:
- Not explaining the steps taken to understand the other's perspective or find common ground.
- Blaming the other party entirely without self-reflection.
- Underestimating the volume and velocity of data.
- Inefficient spatial indexing or query mechanism.

Type · Algorithmic
Given a stream of sensor readings from a wind turbine (temperature, vibration, wind speed), design an algorithm to detect anomalies that could indicate potential mechanical failure. Assume readings are timestamped and may have missing values. - 3
Type · Algorithmic
BP operates a large network of charging stations for electric vehicles. You need to efficiently find the closest available charging station for a user based on their current location and desired charging speed. Design a data structure and algorithm to support this query. - + 1 more questions in this round (sign up to unlock)

System Design
4- 4
Type · System Design
Design a system to monitor and predict the optimal maintenance schedule for BP's global fleet of LNG (Liquefied Natural Gas) tankers. The system should ingest data from various sensors, weather forecasts, and operational logs. - 5
Type · System Design
Design a real-time carbon emissions tracking system for BP's industrial operations. The system needs to aggregate data from thousands of sources (factories, vehicles, pipelines) and provide dashboards for compliance and analysis. - + 2 more questions in this round (sign up to unlock)

Onsite Coding
3- 6
Type · Algorithmic
You are given a complex dependency graph representing tasks in a refinery process. Some tasks can run in parallel, while others have strict sequential dependencies. Write code to determine a valid execution order (topological sort) and identify potential deadlocks. - 7
Type · Debugging
A microservice responsible for calculating fuel price adjustments based on market data is intermittently producing incorrect results. Analyze the provided (simplified) code and logs to identify and fix the bug. - + 1 more questions in this round (sign up to unlock)
