Legit or not? Teach for America calling for an interview

I got a call from someone who claims to be from TFA. They said they saw my resume on zip recruiter and would like to interview me. When I asked where I can see the job description, they told me to check out their website. I checked the website and I don’t think that’s their recruiting method/process? Is this a scam? (Definitely not discriminating as English isn’t my native language either. But I’ve got way too many scam calls and the person on the other end always has a heavy accent. The person who called me has a heavy accent. It was kinda hard to understand what they were saying sometimes.)
