No I don't think it's sufficient, at all. In order for anyone to secure a job in project management, an experience in PM is required.
In project management, certifications are really worthless if you don't have the proper experience to back them.
What I suggest that you do is the following:
- Try to do some project management work in your current job (ask your project manager to delegate some of his routine work to you -all project managers would love to do that)
- Learn more about project management by reading books and articles.
- Participate in the project management eco-system by writing blogs about PM and commenting on other people's blogs.
If you do the above for a year, then you will gain some experience in project management and you'll be able to actually manage a small project from scratch - and then you can search for a job in project management. At this point your PRINCE2 foundation certification will support your candidature for the job.
Again, without experience, certifications amount to nothing. Always keep this in mind!
