In my opinion, CPIB has one of the better HR reps as compared to the other agencies. I have applied for so many which has changed the status to "In Progress" and its still the same for more than a year. "Shortlisted" might mean that they are reviewing your application to see if you are suitable for the job. Your application might have caught their eye but they will still need to review your application to see if can fit the role. If you do, they will call you down if not they wont. So just wait and see instead of speculating
