This is a phone screen. The recruiter introduced some parts of this job that didn't say on the job description. Then It began with some personal simple questions like introduce yourself a little bit and what course you like most in college. After that, he came up with some simple technical questions like what is a class. I used a cellphone and the signal was very bad that day. So the recruiter may didn't hear my answer very clearly. I didn't get any reply after the phone screen.
