⚠️ Common Mistakes to Avoid

  • Don't submit a generic cover letter that doesn't mention Mainspring or the specific role—this is a senior position and they expect tailored applications.
  • Avoid focusing only on your own achievements without connecting them to how you've helped suppliers or cross-functional teams succeed—collaboration is key.
  • Don't underestimate the importance of ambiguity management; if you can't provide examples of thriving in unstructured environments, your application may be overlooked.
