Continental Angular UI/UX Developer interview questions

Applied via Linkedin get invite for interview, first interview was technical there we 3 interviewer and all are very experienced takes. In the end one of them said will be get back to you next week with next stage but after constantly (weekly) following feedback for next stage in the end with a generic rejection email from HR. Technical interview was very good and I am 90% sure that will proceed with next stage as all the skills and JD match with my expertise and past experiences. Dont know what happened behind the scene.
