Continental Senior Software Engineer interview questions

Hiring process is so slow it's almost a month already and been asked to wait. HR is not accomodating and unprofessional. Attended several interviews - HR, panel, and interview with Project Manager. Questions were mostly case to case basis and experience background. For the panel interview, they will ask you to make an app for presentation. After the interviews, HR will ask you to answer their assessment exam (take home). They already ask me for some requirements but still will not say if you're being hired or not. What a waste of time and efforts.

Telephonic round - technical 2 technical rounds Face 2 Face 1 Manager round question were on c programming , macros, pointers, c++ programming , classes, polymorphism ,ARM Neon instructions, image processing algorithms and code optimizations. Few questions were on the projects that i worked on.
