Only in very very rare cases, I came across companies who sent automated no-reply rejection emails to applicants when the role has been filled or when they were not shortlisted.

Most of the time, applicants received an automated no-reply email indicating the applications have been submitted successfully and they will only be notified when shortlisted. No timeline given.

At least some who gave a timeline (such as shortlisted candidate will be notified within x weeks) will make it easier for job seekers to manage their expectation and application process.

Be it be a case of genuine 'profile collecting' or 'role internally filled but job posting not taken down', having a timeline will make it much easier for everyone, and job seeker can move on and mark as case close.
