About the role
This interview covers services that cross operator boundaries, including roaming and domestic or international interconnect. Interviewers assess your grasp of service flows, your use of shared technical evidence, your care with usage records and your ability to coordinate a launch or fault with external partners.
How to prepare
- Review registration, call, messaging and data flows when a subscriber uses a partner network.
- Prepare a cross-operator fault where traces or test cases established which side owned the fix.
- Think through how you reconcile usage records and investigate timing, rating or duplication differences.
- Practise describing entry criteria, test coverage and sign-off for a new partner launch.
Common mistakes
- Treating registration success as proof that every roaming service works.
- Escalating to a partner without timestamps, subscriber conditions or trace evidence.
- Reviewing settlement differences without checking record scope and time alignment.
