The Danger Zone: Top Reasons Candidates Fail

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

  • Ignoring the capital expenditure and operational costs associated with battery storage.
  • Suggesting a split budget that results in neither project achieving full ROI
  • Focusing only on one aspect of differentiation (e.g., just price) without a holistic view.
  • Underestimating the importance of ancillary services or amenities at charging locations.
