Samsung Semiconductor Inc (US) Senior Software Engineer interview questions

First there was an online assessment, after which I was called for 4 hr long interview process. First was a panel interview with 2 people having different expertise were asking me questions. Did not get selected after the first round.

One phone screen. It was taken by a inexperienced engineer asking esoteric questions. Questions were based mostly on his knowledge rather than my CV. One of the required skill sets was scala. He was more interested in implementation details of the language. It was more like asking load and store operation for cpu. Phone screen was for half an hour.
