There is no cutoff and your application is considered as a whole. Some offices may have automated the process but for sure a lot of work is still done manually. Thus make sure that you have the keywords in your resume (universities, brands, etc). The most important is - the ranges for these criteria are not set in stone. There may be a lot of factors influencing the cut-offs:
- Targeted recruiting. For example, the Firm may decide to hire more MBAs rather than pure experienced hires. Or the Firm may hire more female candidates and thus more females will pass the screening. Some offices have the special recruiting cycles for technical and non-technical graduates
- Competition - for example among all MBAs they will hire more graduates from top universities. And among them, the screening will pass only the people whom their ex-mbb classmates personally recommended.
- Office specifics - in some offices like New York it's hard to pass the screening even if you have a referral
- Economic cycle - in a bad year it gets harder to get in
...and many others. You should do your best (Resume, CL, get a referal, smartly select the preferable offices) and keep your fingers crossed.
