Quantexa Interview Questions
& Process

Quantexa's interview process for a Product Manager role was logical and transparent from start to finish. The experience was well-structured, with each interviewer balancing technical competencies with a genuine effort to get to know me as a person. The process consisted of 4 stages: 1. Recruiter Screening Call. 2. Hiring Manager Interview. 3. Case Study Presentation & Q&A. 4. Head of Department Interview. Jonathan Holmes from the Talent Team was my primary contact and was excellent throughout. I was provided with comprehensive context and preparation materials before every stage. Most impressively, I received post-interview feedback in less than 24 hours every time. The speed and clarity of their communication truly set them apart from other companies.

The interview process was great overall. Starting with the initial call with Jonathan Holmes and ending with the final interview with Faisal Kamal and James Cater. They kept me informed about what to expect at each step. Faisal and James were really friendly and made me feel comfortable during our chats. It was nice because sometimes interviewers seem uninterested, but they were not. They were open and honest the whole time. I also got fast and useful answers when I had questions, which made everything feel smooth, professional, and enjoyable.

The interview process kicked off with an introductory phone call with the talent partner to get a feel for your background beyond the resume. If it seemed like a good fit, you'd move straight to the next stage. Then came a coding assignment, which you had seven days to complete using Scala and Spark, including writing test classes. The problems were pretty standard, mainly checking your grasp of functional programming since Quantexa heavily uses Scala/Spark. You'd submit your work via an online portal, and they'd let you know within a week if you made it to the final round. The last stage was a deep dive, lasting up to two hours with at least two senior engineers. It had three parts: first, a 15-minute presentation of a past project, followed by Q&A. Second, a review of your coding assignment, discussing potential changes, tests, and your design choices. Finally, a case study exercise mimicking Quantexa's daily tasks, focusing on your reasoning, detail-orientation, and problem-solving skills, rather than heavy coding.

I applied through an external recruiter. The first round involved a discussion with the Hiring Manager and an engineer, covering many technical aspects from the job description, with a strong emphasis on Kubernetes. I answered all questions easily. There was also a live coding assessment that was straightforward, using a LeetCode style. The second round was a take-home practical test where I had to deploy an application in Kubernetes and detail all the steps, which was quite simple for someone experienced with k8s. The third round was meant to be a presentation of a past work or personal project to a panel of engineers. They seemed very interested in moving forward, but then communication slowed down, and they stopped responding to my emails even after I followed up multiple times. Despite providing comprehensive answers in the interview and the practical test, detailing everything I did, they ultimately stated I lacked sufficient experience and my salary expectations were too high, even though they were within their stated range. It felt like a complete joke, as if they were just looking to hire someone cheap for a senior role.
