After the HR round, I had an interview with the line manager with explaining that the next stages will be explained by the HR definitely within a few days. After a week I followed up, just to receive an automated email that they are not available and the answer will be delayed, then I never got an email. After a while I followed up again, with another automated email that the person in charge isn't available, but no follow-up either. Just completely got ghosted. The company keeps reposting the same position on the job boards for many months, and I doubt it is a real job posting.
