Unless you're with a really decent operator, it's not the best job to have in aviation. You won't get any credit for doing things right but as soon as anything goes wrong it's your head on the block. Can look good on a resume though.
As listed above re points to pay attention to for the interview, also an opportunity for you to gain some inside knowledge on your employer. You may find CASA have concerns about their maintenance, you could also find out if bills are paid on time which may be relevant to you later on.
If successful, you will be watched for the first few months. Expect phone calls and possibly a visit if they have any concerns.
In some ways you are CASAs man in the company you will have the "get out clause" explained to you if you're approved. Any chief pilot knows what I'm talking about.
