T-Mobile Software Development Engineer In Test interview questions

I had this interview through a recruiter. Recruiter was able to get me an interview in two days. Hiring manager called me. The first question was from my resume, what did this application do? I was able to explain. What tools were you using there? I explained about Defect management tool, Pivotal, Rally and QC...he was impressed and said that they are also using Rally and QC. Overall it was more of a conversation than interview. I think it went well except one or two things. He asked me about different headers in HTML and function of F12 key which I was not sure about.... took a while and answered F12 is used to open developer's tool. After 4 days, I heard back from my recruiter that they want to call me for in person interview next week but next day my recruiter called me again and said that unfortunately they are not moving forward with me anymore!
