⚠️ Common Mistakes to Avoid

  • Submitting a generic resume that doesn't emphasize Azure, microservices, or migration experience—this role specifically requires cloud-native skills.
  • Failing to mention mentoring or leadership experience; the job description explicitly asks for technical guidance to other engineers.
  • Neglecting to showcase performance profiling and memory analysis skills, which are critical for enterprise-scale applications.
