There are two important principles here:
- All job postings are approximations
- There are no guarantees about who gets invited for interviews
Let's consider the 'standard' interpretation of job requirements. If it says "must have" or something similar, it means you need these to be considered. If it says "asset" or "nice to have" or something similar, it means you don't have to have them - your chances of getting interviewed (and getting the job) are higher if you have them than if you don't., and higher still the more you have them. Companies usually try to write descriptions so they think they will get plenty of applications with the minimum requirements, and some people applying with some of the extras.
But all job postings are approximations. That means that if they get no applications from people with the "must haves" then they may invite for interview people who don't have those qualifications, but maybe come close. LIkewise if twenty people apply, all of whom have all the 'extra' qualifications, then even having all the extras won't necessarily get you an interview. They will invite the people they like best.
So, in short, you never can tell. There are no guarantees about who gets invited for interviews.
