Is it possible to switch internally without interviews at the same role(SDEs)?
Review models are generally set at the vp level, so generally speaking you can move around freely under the same vp. There are exceptions to this and I know rajesh is working with his vps to look at allowing free transfers across his orgs but that is not implemented yet.
If you are moving teams within the same org, you will have informational with hiring managers/members than real interviews. If you are moving to different teams and org altogether, you will go through a loop and hiring decision.
Within the same org it's a lot more likely, if you get an interview there is a low chance it will be technical. Under your skip from what I understand you're able to move around easily.
Even for a new joinee?
Under your skip if you play it as being really interested in another team and their work, maybe. Switching in a short amount of time is typically a bad move though.
Yes, if you're staying within the same org.
