Samsung Electronics GPU Software Engineer interview questions

Talked to a director on Linkedin, and had a video chat. Resume sent. However, I was asked to wait for follow ups forever. In between have messaged the director a lot of times but the director just told me no need to ping other recruiters. Have moved forward with another offer. Very bad experience, it looks like every hire/interview schedule they have to talk to KR HQ. Makes me feel negative to work here.
