The Danger Zone: Top Reasons Candidates Fail

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

Failing to consider statistical significance or test duration.
Using arbitrary criteria (e.g., 'sounds cool') instead of strategic alignment or user impact.
Giving a generic answer not specific to Monumental or the industrial domain.
Focusing only on the technical details without discussing the interpersonal dynamics.
