There are two main possibilities.
- The job advert asks you to ring the company for an application form.
- Or, usually a little later in the process, you have to ring up and arrange a time for an interview.
Either of these cases can be entirely straightforward - just a matter of getting a small administrative task done. But depending on who you speak to, there could also be questions of a sort you wouldn't otherwise expect until you fill in the application form or go for an interview.
These could be either factual - "what's your educational background?" - or human - "what interested you particularly about this job?"
It makes sense to be prepared before you make the call, just as you would before an interview.
