How to Pass the APG Software Engineer Interview in 2026

The APG DNA (TL;DR)

The transition to 'Pensioenen Vernieuwde' anchors APG's evaluation, targeting experts who can navigate complex pension reforms. Recruiters signal for the 'naming the trade-off you rejected' technique when balancing risk and long-term societal yield in 'Vermogensbeheer'.

Past evidence of ownership, influence, resolving conflict.

The Danger Zone: Top Reasons Candidates Fail

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

Failing to design for idempotency in payment transactions
Focusing only on general tech stack rather than the social impact of pension management
Failing to implement an eviction policy like LRU
Neglecting to handle lists of unequal lengths
