I interviewed at Low Carbon Contracts (London, England)
Interview
It was a great process but stretched over five months. Strong communication and it seems they have fostered a supportive environment within their company. I am heading into the technical task interview and want to find out more.
I applied online. I interviewed at Low Carbon Contracts in Apr 2026
Interview
The interview process started with an online screening test on TestDome (Django, Python, HTML/CSS, and React).
This was later followed by a live coding session and technical discussion.
The coding task was a Python problem on multiple customers shopping across multiple supermarkets. The goal was to compute the lowest possible basket cost per day, taking into account time-bound discounts and selecting the optimal supermarket, with a delivery-time tie-breaker.
There was also a system design question about building a reliable service to sync payment data from an internal database to a third-party API, where the external system may be unavailable or unreliable.
Additionally, there were questions on debugging issues in React applications.
Interview questions [1]
Question 1
If you got a response from the external API that a timeout happened - how would you handle that?
How would you let users know that an attempt to sync failed?
How would you investigate a slow sync?
Do you follow any principles (DRY, KISS, etc) when writing code?
Received a Criteria Cognitive Aptitude Test (~15 mins), which tests verbal, numerical and spatial reasoning. Havent done it yet. Before this was just a CV and a few questions about reason for applying.
