T-Mobile Analyst interview questions

The Talent Scout sent an email to make a schedule of the interview. In the interview, she introduced the company and asked questions. Then she asked if I have any questions. The whole process is about thirty minutes.

Phone screen with recruiter, face to face with director. Then F2F with 2 managers and an "observer". The observer asked questions too and was the team member. When I sent the thank you letters the VERY next day after the last interview, one of the managers's email was invalid (and, he was the only one that gave me a business card.) And. I now see the director's job posted. ( INTERESTING!!)
