Audit Associate/Intern Skills

I am a career changer closing in on the home stretch of getting my MACC.  I am currently looking at internship opportunities for Winter 2016, as well as entry level jobs in audit upon graduation.  Having a few years of career experience already (insurance back office operations, not accounting), I recognize that I am not getting a lot of the practical, hands-on skills in my degree program that will be necessary for success in a role with a firm.  Can anyone talk about a few of the things they wish they'd known how to do when they took their first job, or things they wish new associates could do on day 1?  I'm heavy on theory/light on application and just looking on ways I can develop in the next few months so that I can contribute to the team quickly once I get a job.  Any advice is greatly appreciated.
