I've interviewed and hired dozens of software developers. Here are a few quick and easy tips to stand out.
  1. Make your resume accomplishment oriented, not responsibility oriented. Include measurable outcomes (i.e "designed and implemented authentication service that reduced response times by 37% and errors by 18%")
  2. When emailing resume include short cover letter in body. This is your chance to let the company know you aren't just blindly sending your resume in. Highlight particular items in your resume that are applicable to the job you're applying for. Resume should be pdf attachment.
  3. Answer emails quickly.
    You don't need to respond within minutes... An hour or two is fine. Quicker during current exchanges.
  4. Have a flexible schedule to meet with potential companies.
