The Danger Zone: Top Reasons Candidates Fail

Based on our database of Telenor interview outcomes, avoid these common traps:

Single point of failure in the gateway design.
Not considering potential cycles or negative weights if applicable (though unlikely here).
Relying solely on batch processing for fraud detection.
Failing to articulate the technical learnings or how the experience changed their approach.
