Rokt Machine Learning Engineer Interview Questions
& Process

Rokt was super responsive and easy to schedule with, always getting back to me fast with feedback. I really liked the people I met, both online and in person. The process was quick, usually getting results the next day and setting up the next interview. A cool thing was after a few rounds, HR sat down with me to go over the feedback from each person I talked to. That openness was awesome, and the feedback was always fair and helpful. Even though I ended up taking another job for my career path, Rokt's HR team really tried hard to get me to join, which made me feel respected and valued. I felt totally supported by them.

I went through some aptitude tests, then a HireVue interview, and finally a take-home assessment that I had 72 hours to complete. The problem was pretty straightforward but had a tricky part. The downside of this AI-driven hiring approach is that I didn't interact with anyone during the whole process. I even questioned if it was a scam. The hiring process could have been better, as I didn't receive any feedback.

The process started with a personality quiz, which I refused to do. Then, a third-party recruiter contacted me, and I spoke with an Engineering Manager, the only positive interaction. I had a choice between a take-home LeetCode or an in-person LeetCode; I chose the latter. These were challenging, especially for Sydney's tech scene. I completed them successfully. Next, I had an in-person coding interview with the Engineering Manager, which was straightforward, and we discussed my past work's impact. The ML interviewer seemed to have only taken an online course and went through a checklist without much depth. The Systems Design round was difficult due to my lack of web-scale experience; I struggled with designing a system when told I couldn't access certain data and was criticized for my lack of knowledge. Despite failing Systems Design, I was downleveled for the CTO interview. During this interview, it became clear the company is primarily sales-driven with basic ML. The CTO described a 'scrappy startup culture' unsuitable for their size. They did not send a rejection email; my recruiter had to follow up.
