If you have been shortlisted, the wait shouldn't be too long. I applied in mid-December and about 3 weeks later, I was given a date for their Initial Test, which I completed a few days ago.
The projected selection schedule I was given looks like this:
Initial Tests: January - February
Aptitude Test: February - March
1st Interview: March - April
This is unless you are holding a CPL/fATPL/MECIR and the like... I have friends who hold these licenses and have applied, but have not heard back yet. Not sure why.
