If you want to display insight into the world of consultancy, I'd suggest....1. I'd hope my current skills would be enough to get me on a billable project position, but no doubt there would be parts if that job that I would not be up to speed on. Priority one would be to do some studying to cover off those gaps.2. Second thing I'd do is work out what skills and experience I have that I might be able to share with other consultants - perhaps organise an after works session in the office where I could talk about my previous role with one if our clients.3. Third activity would be to read up on our wider capabilities and try and establish contact with some peers in those teams. That way if there are opportunities for the firm to cross sell, I'm more likely to recognise them and know who to go to for advice on qualifying them.
