There is no way to interpret how the company is using the system. I have experience within my own company different styles.
Some HR specialist will quickly review any application and reject any that are below a standard immediately. Then they pass on all the rest to the hiring team once the time period the posting must remain open has ended. So 25% are rejected in less than 24 hours, but no progress is noted for two weeks, until the team can go through all the ones not rejected. Then many are quickly rejected and half the survivors are called in for interviews, but those that aren't called in are not rejected until the hiring team knows they have interviewed enough good candidates. It is possible to have almost zero chance of getting the job, but not be officially rejected for weeks.
In other cases they will perform a daily review. and only send the top ten to the hiring team. So you could survive for a few days, but eventually fall out of the top ten if there is a late wave of applicants.
You may also find out that it is hard to get the contact information for the person making the decision. They may be hundreds of miles away from the hiring team. So finding somebody to ask can be very hard. If you do know somebody in the company, and they can recommend you, they may have better luck getting a more accurate status.
The best advice is to apply to multiple places at the same time. Also don't get too attached to one company, unless you already have a good job, and are just looking to change jobs if a great opportunity if offered.
