Sure, ask me anything and i will google it.
But in all seriousness, the best way to tell is by giving them a small task, asking for previous work, or trying the applicant for one day while having a close look -- other than that you will waste your time.
If seriously need to do, he can also get small work hired by other guy and get work done, so in fact, if really need to tell anything misleading, he can do by anyways.
