Hi Bec,
Not sure what position you are currently looking to fill, but I would interview this person and find out as much as you can about their experience in both
HR and the Defence Force.
Whether they are suitable will depend on how their military and
HR skills can be applied to the position you are recruiting, and to your organisation. You should also look at other factors such as your workplace culture. The culture and practices of the military are often very different to those in business.
if you feel they have the potential for a senior role but need more experience first, see if there may be an alternative role at a lower level you could offer them. Make sure that they are provided with the opportunity to apply their higher level skills if you do this, and plan for their development into a more senior role further down the line.
At the end you need to decide what will be best for your organisation.
Hope this helps.
Cheers
Michaela
