It is hard to say for sure, but probably it is lesser advantageous for you if you mention your friend there. But you can ask your friend! If you already know, who will interview, you can ask your friend and ask everything from him what is important for you!
Guys working in such places want to see a long-term commitment from you, and they will prefer your CV to what you say to them. "Long-term" means maybe 5 years for you, for them it means "until retirement". There are hundreds of similar minor differences between your terminology and theirs.
They tend to know that they can be used as a "temporarily shelter" for life cryses or for random bad times on the job market, and they are not happy with it.
With other words, do not hope that you will get this job easily only because it is easier. You still have to fight, and now you need to fight on a front you are lesser familiar.
The best what you can do in your favor, that is some improvement of your CV to their focus, and also what you say.
The most important thing of such places is that the work... uhmm, well the work sucks. Yes, there is no better to say. You will also need to continously and stable fulfill a lot of regulations, many of them seem meaningless for you, but no one will ask your opinion. That will take years until you will be able to bend them on the ways they are not so rigid, and you have no plan to work still there.
With what you can play in your CV, is how much detail do you give from your previous workplaces. Obviously you want to prefer the previous times where you worked for the government, or for a company working for the government. Give much more details about these.
You must be team worker. So, talk a lot about, what "we did" and at most a secondary level, what "I did".
Try to see this work, as if you would see the work more close to central parts of the Big Human System would be a career step forward in your system. That will be believable for them, because also that is what they do.
Needless to say, never mention that they pay lesser as usual. For you, the job is important - being a trustable screw inside the machine -, your salary is just happens and that is it.
I think roughly that is what maximizes your chances.
However, again what unemployed people tend to forget, until you do not have the signed work contract in your hands, you are not employed and thus you are applying for jobs.
