The Danger Zone: Top Reasons Candidates Fail

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

Blaming the other party or presenting a one-sided view of the conflict.
Focusing only on personal career goals rather than alignment with Vattenfall's mission and supply chain needs.
Giving a generic answer about wanting to work in sustainability without mentioning Vattenfall's specific context.
Focusing only on internal manufacturing issues and neglecting upstream (suppliers) or downstream (logistics, installation) factors.
