Robert Bosch Software Engineer/Senior Engineer/Specialist interview questions

I was called for UI Developer role but the interview went for ASP.NET C# . The interview began with asking about my projects and stuffs what I did . It would have gone okay if the interviewer was really interested in taking the interview . It seems that he wasn't interested at all . He was too busy in picking up his personal calls , going out every time leaving the interview session . I was not sure that do Bosch really wanted to hire or they just conducting the interview to make a joke of the applicant.
