"Do Not Overstate Your Capability," but do make sure to highlight the various areas in which you have polish. The interviewer may ask what experience you do not have, which you can then explain to be a critical reason for wanting to find a new job. You WANT them to see you as motivated and eager to learn, not as someone who thinks too highly of themselves. If you already knew it all, you likely wouldn't be in the position of interviewing for a job.
