Continental Software Engineer Development interview questions

The first interview (ca. I hour) was with HR. The experience was good. At the end of the interview, I was told this position received a lot of good applications, but HR will transfer my application to the hiring manager. After two weeks, I was invited to the second round interview with the hiring manager. But in the interview, the hiring manager was not present, only two employees interviewed me. They were nice, asked me about my current and previous projects. Not difficult to answer. About two weeks later, I got rejection. The job description was poor defined. After the first round interview, the job ad was withdrawed. But, after I got the rejection, the job ad with some modifications was again on their homepage.
