Be ready to go over:

• Data integrity and validation techniques.

As an Operations Analyst, your primary responsibility is to ensure that the trading infrastructure is running optimally. You will spend a significant portion of your time monitoring data feeds and executing operational checks to ensure accuracy. If an anomaly occurs, you are the first line of defense; you must investigate, document, and escalate the issue to the relevant engineering or trading teams.

Collaboration is central to your role. You will act as a bridge between the technical teams building the systems and the traders using them. This requires not only technical knowledge but also the ability to translate technical jargon into business language for various stakeholders. You will often lead small projects to improve operational efficiency, such as automating manual reports or refining monitoring dashboards.
