Process

I applied online. The process took 7 weeks.

It was a smooth interview process with very clear and transparent communication between every stage. The HR team was very nice. The interview process consisted of 5 parts:

Online application with CV.
HR screening interview with Talent Partner.
Technical Assignment in Scala and Spark (7 days to complete) - no prior experience in Scala required.
Technical Interview made up of 3 parts: Timed presentation of previous project + code assignment review + business case study.
Final informal chat with Delivery Manager.

They'll make a decision that changes your life and never put their name on it

Data Engineer • Former Employee

Pros: The work itself was genuinely interesting and the technical problems were engaging. In my experience, many of my colleagues were smart, talented, and good to work with day to day. Early on, the onboarding and mentorship process felt supportive and I was recognized positively for my performance.

Cons: In my experience, the process that led to my termination moved very fast and left me with serious unanswered questions. I personally never received documentation that, in my view, clearly explained or supported the basis for the decision. When I formally requested it, what I received felt thin and incomplete. I also believe a manager whose own guidance directly contributed to the situation was involved in the termination decision, without any independent review that I'm aware of. In my opinion, similar workplace relationships were not always treated the same way internally. I was personally going through a difficult time before this happened, and in my experience nobody checked in or paused the process. When I later asked honest questions about how the decision was reached, I was told there was nothing further to share. To me, that says a lot about how individual employees are treated once they're no longer with the company.
