⚠️ Common Mistakes to Avoid

  • Submitting a generic CV without tailoring to hydrology/surface water; avoid listing unrelated experience.
  • Ignoring the 'roster' nature of the role—applicants should express flexibility and readiness for short-notice deployments.
  • Failing to demonstrate practical, hands-on modeling skills; theoretical knowledge alone is insufficient.
