Positive ExperienceGot Offer

Process

I applied through an employee referral. The process took six weeks.

It was a very streamlined and pleasant process.

An initial HR screening call with general questions about your background and motivation for joining the company.
A take-home coding exercise predominantly in Scala. If you don't have any experience in Scala, they take this into account and provide useful learning resources.
A 2-hour final interview with a few general motivation and CV questions, a presentation you've had to prepare beforehand, and walking through your coding assignment and possible improvements.

A member of their internal recruitment team is your point of contact throughout the process. I had Sumayyah, and she was great! She was very responsive, helpful, and friendly. Overall, it was a great process.

Quantexa Work Experiences

Good benefits but not very technical

Data Engineer • Former Employee

London, England

November 28, 2025

Pros: Benefits are nice, salary's decent, culture is pretty good for the most part (although getting progressively worse as the company grows). You get to interact with clients a lot, so it's a great opportunity for someone that wants to gain consulting experience.

Cons: The data engineer position in Delivery consists in implementing the Quantexa product for different clients. The product has been developed so that little to no code is required for its implementation, mainly writing configuration files or copy-pasting code from one repo to another, so as a consequence the work in Delivery tends to be tedious and repetitive. Speed tends to be prioritized over quality, so good practices are often overlooked. You get to learn a lot about the internals of the Quantexa product but not so much about general data engineering. All in all, not great if you're looking for challenging work or your priority is to gain transferable data engineering skills.

A good place to be for a while

Data Engineer • Current Employee

Cons: Configuration/Coding/Deploying the same solution can get boring after some time.

Everything has become much more corporate

Data Engineer • Current Employee

London, England

Pros: There are good development opportunities in some departments, nice people, and some good perks.

Cons: As it has grown, the company has become much more corporate, and on some delivery projects with difficult clients, junior employees are left to fend for themselves with little guidance or development.
