Whether private or public sector, it seems like some places are always advertising the same position. I assume there are a number of explanations for this, such as:
1. They cannot find applicants they want
2. Nobody wants to work there
3. They hire people but there is lots of turnover
3. They are growing in responsibility/workload and are constantly seeking new staff
Can anyone with an inside perspective on this share what is going on in these places?
