Give them a call or send them an email guys. They're pretty approachable. You have the right to hear something within a few weeks. They should be very happy that you're taking the effort to apply for the job. Good luck with the rest of the assessments!
Thanks NLP, I called on Friday (assuming they were finishing for Christmas) and they said that if I don't hear by January 3rd give them another call! However like a reply above, I've had friends who've had their results within 10 days! Just annoying but understandable now the DEP application is open again. They must be snowed under!
