Mistakes that kill Mariana Minerals applications

  • Don't send the same CV you sent everywhere else. Whoever reads applications at Mariana Minerals can tell, and it's the fastest rejection there is.

  • Lead with their problem, not your ambition. Mariana Minerals is focused on is growing — show you understand that.

  • Applying and waiting = silence. Follow up at day five — it roughly doubles your odds of a reply.
