I'd say Yes to take along your CV.
It will help you as an 'aide memoir' in the interview, especially if they ask you about your current and previous positions - which they should do if they are good interviewers. But take it for your purposes, not for theirs, unless they have specifically asked.
I would have a list of questions ready, many of which should be answered in the interview. And it is ok to genuinely not have any questions, as an interviewer,it is really easy to spot those questions that have been asked for questions sake.
Ask questions about:
- who will you be working with, are you within a team, eg
- ask if the role is new or is a an existing role that has become vacant. I have been asked by candidates why a role is vacant - have had no problems in telling people the reasons why.
- ask about the firm's attitude to work life balance
- ask about the firm's corporate social responsibility
- ask about internal communication i.e is there an annual staff conference, away day etc?
- ask about the interview process - will there by a second interview?
Just make sure you are as prepared as you can be - look on their website, understand a little about the industry that they are in etc.
Try and pre-empt questions that they might ask you.
And try not to be too nervous. At the moment, in pretty much every industry it is a 'candidate's market' so you are in the stronger position. Treat it like a two way interview process i.e it is just about you finding out about them as it is them finding out about you.
Good luck!!!
