Is this unusual

[Betterdaysarecoming71]

I've recently applied for a job,I've been offered an interview. I saw today that the organisation still has the job advertised with the closing date being next month.

You haven’t got the job, just an interview. Sounds perfectly normal.

Not unusual at all, you just have an interview, they still need to keep options open!

not unusual at all, you've been offered an interview not the job

They will only stop advertising the job once they have a suitable applicant. Good luck!
