OpenX Interview Guide
Everything we know about interviewing at OpenX: the process stage by stage, what each round tests, and compensation by level.
Interviewing at OpenX
What the process looks like, and what OpenX is really testing for.
At OpenX, you go through multiple interview steps that include recruiter screening, then technical and domain-focused sessions, and finally an onsite loop with several back-to-back interviews. The distinctive part is how tightly the technical topics map to the role context, with very prominent testing and ad-tech domain coverage alongside core programming and data skills.
Across the extracted topics, the interviews heavily emphasize SQL, Java, algorithms, and technical vetting or technical screening. You should also expect Excel and QA Engineering topics to show up as top items in the question set, plus Real-Time Bidding (RTB) and Machine Learning topics that are each at the highest prominence level in the extracted data.
The reports indicate a multi-stage timeline that leads into an onsite interview loop, and then additional onsite structure that includes data-analysis and presentation components in at least one described onsite loop. From the candidate reports provided here, the offer rate is 0.0%, and positive sentiment is 39.3%, so you should treat feedback and iteration as essential to your preparation.
The highest prominence topics are not generic-only, they include RTB and QA Engineering alongside SQL and algorithms, so you should prepare to connect your technical answers to ad-tech and quality or data workflows, not just solve coding problems.
