Many big companies are like this. The criteria written in the recruitment notice are the criteria for HR screening. If two people compare that one of them is not up to standard, HR will naturally filter out the one that is not up to standard. This is normal. HR is required by the superior. Unless you are an introvert or an awesome director and supervisor personally find you, it is difficult for you to submit your resume without meeting the standards. HR is also a part-time job.
