You've made it through the first part of the application process. Now, companies will review your application and invite you back for interviews if they decide that you are a good fit for the company. Typically, most companies invite applicants back for a few rounds of interviews. This ranges from behavioral to technical interviews.
If you don't hear back for a while, it may simply be because a company is trying to process a lot of applications. Don't stress about it, you can always send recruiters follow-up emails to check on your application status. If a company decides that they do not want to move forward with your application, do not worry! Recruitment is tough, and it's not always the end of a line if you are turned away from a certain company. Keep applying, learn from your mistakes, and find the company that is the right match for you.
