In case you are wondering why the Indian media get so excited about the THE and QS rankings and not about those that are just as good or better such as Leiden Ranking, RUR or Nature Index, see this from the University Grants Commission.
Note that it says "any time" and that only the Big Three rankings count for getting Assistant Professor jobs.
"NEW DELHI: University Grants Commission (UGC) has come up with, UGC Regulations 2018, which exempts PhD candidates from having NET qualification for direct recruitment to Assistant Professor post. This new draft regulation is known as Minimum Qualifications for Appointment of Teachers and Other Academic Staff in Universities and Colleges and Measures for the Maintenance of Standards in Higher Education. Further the Commission has also listed 'Ph.D degree from a university/ institution with a ranking in top 500 in the World University ranking (at any time) by Quacquarelli Symonds (QS), the Times Higher Education (THE) and Academic Ranking of World Universities (ARWU) of the Shanghai Jiao Tong University (Shanghai),' as one of the criteria for Assistant Professor appointment."
