I am an entry level software developer and often during job interviews they use to ask me what is the difference between soap and rest api.

I tried to search it online and I did not find anything that satisfies me 100%; what I understood is:

1. soap uses different protocols, rest just http/https
2. rest accepts several data format, soap only xml
3. rest is stateless, soap not

Are all of them correct? Is there any other relative difference?
