If his application was accepted online; he should receive an email requesting a time and date for a telephone interview. They receive thousands of apps, so sometimes they get back to you immediately; and sometimes, it takes a couple of weeks or even longer.
The telephone interviews last 15 - 30 minutes. Tell him not to be nervous; they are ALWAYS very nice and want him to suceed. Just be very positive and relax. After that, he should know by the first week in December; however, I suspect it would be sooner.
Good Luck!
