⚠️ Common Mistakes to Avoid

  • Don't overemphasize backend experience without showing strong React skills—this role is frontend-heavy.
  • Avoid generic statements about 'passion for clean energy' without connecting it to your technical work.
  • Don't neglect to mention testing experience; it's a key requirement and often overlooked by candidates.
