Samsung Electronics Supply Chain Analyst interview questions

The interview process was fine, i gave 3 rounds of interviews and I think they went pretty well but what really disappointed me was the ghosting that followed after, I mean at least let me know what's happening, even if I'm rejected, I messaged each interviewer at least 10 times to follow up so it was not a great experience overall. And this is supposed to be their headquarters in NJ

The 1st is more technical. Questions about how to handle specific cases. The 2nd is more about knowing who you are, like personality. The communication between 2 groups of interviewers might be limited, because the 2nd round interviewers were surprised by my salary expectation, while those of the 1st round said no problems.
