Why they ask: Checks that you understand the basic purpose and mechanics of the system you will work in daily.

Why they ask: This tests the exact day-to-day process and whether you can work methodically.

3. What typologies of suspicious activity would you expect to see in monitoring alerts?

Why they ask: Typology knowledge helps you recognise genuine risk quickly.

4. What is the difference between unusual and suspicious activity, and what threshold applies to forming suspicion?

A sample answer to question 1

What is transaction monitoring and how does a monitoring system generate an alert?

Transaction monitoring is the ongoing review of customer activity to detect behaviour that is unusual or might indicate money laundering, terrorist financing or fraud. It is required under the Money Laundering Regulations 2017, which expect firms to scrutinise transactions throughout the relationship to make sure they are consistent with what the firm knows about the customer. A system applies scenarios or rules to transaction data, for example cash deposits over a value within a number of days, rapid movement of funds in and out, or payments to high-risk countries. When the activity breaches a threshold, it generates an alert that goes into a queue for an analyst. The rules are calibrated by risk, with different thresholds for different customer segments. Some firms also use behavioural or machine-learning models to compare a customer against peers or their own history. The alert is not a finding of suspicion, only a prompt to investigate, and my job is to determine whether there is a reasonable explanation.

Common mistake to avoid: Treating every alert as suspicious; not knowing why monitoring is required
