I had that for about a month on about 10 different applications I had submitted. after about 3 weeks some changed to "all positions have been filled" and then a week later I got an email from the recruiter about wanting to set up an interview and I emailed her back expressing my continued interest. The following morning I got a call to set up a date and time. After that all of my applications that still said "You have met the minimum qualifications" changed to "Your resume has been forwarded to the hiring manager." The one position I did get call for about an interview has been changed to "The hiring manager is in the process of scheduling interviews." So I guess the short answer to your question, in my experience would be, about a month.
