It used to be basically impossible to get one, but that has changed recently with these fast track processes. However, each location has different rules and durations for the process and it's common for rules to change during application; or for the process to take years longer than the official length. Not to mention processes that "freeze" and there is no feedback on why it happened. All of which end up making the whole process extremely hard. Moreover, the exact implications of getting PR are not clear in regards to rights, taxation, or other obligations. It will probably take a non-trivial amount of time for things to stabilise and be clearer.
