It's a lie, vacancies are updated at least once a week. Go to an appointment with a specialist. If you are looking for a specific job, then contact the head and he will find such a vacancy.
They are not looking for a job and should not, as I understand it. The database of vacancies is not being cleaned, I honestly typed in the vacancies terminal, spent half an hour, and then noticed that there is a date in the upper corner, almost all vacancies last year.
