Process
I applied online. The process took 3 weeks.
The interview process is very streamlined, professional, and thoughtful. After applying online, a call was scheduled with Sumayyah Khan, who explained everything in detail about the company, role, and the interview process.
The overall process contains 2 stages:
- A take-home Spark/Scala coding assignment.
- Once shortlisted, a 2-hour interview call with recruiters who are really friendly and knowledgeable, and who made sure the entire process was smooth.
In this round, I was asked to prepare a presentation on a data engineering problem which I solved as a Lead, then a discussion of the code which I submitted, and finally a business case study discussion. Throughout the process, Sumayyah was really helpful and provided quick responses for all my queries.
Questions
There were Spark and Scala questions, and questions related to the presentation that I prepared.

Strong product but troubled by poor management
Lead Data Engineer • Current Employee
London, England
July 24, 2026
Pros: Industry leading product in big data analytics. Great engineers to work with and some really good teams especially in r&d. It was good for a long time but those days are gone especially in delivery
Cons: It's gone downhill massively in recent years especially in delivery. As other reviews have mentioned the company has been canablised by non technical middle managers with fancy job titles. In delivery you could be on a project that is hell on earth for 1 year + with a nightmare client and basically nothing from the company apart from get it developed asap. Iv heard of some mad horror stories in delivery recently. Many delivery managers are essentially useless and the engineers have to do their job for them.
There are too many nonsense internal 'initiatives' and your punished if your on an insane client project with no time for it. Return to office mandates to sit on teams screen shares with developers in 4 different countries? Many great devs have left for this reason alone and upper non technical 'management' just ignore it. Pushing AI heavily instead of hiring new developers or replacing devs who have left. It's not clean how it's going to work at all. It's not uncommon to be in a crisis delivery project working 10+ hour days for weeks/months unend and you will still get punished for not sitting in the office
