I worked with two project managers from their US team STA (Samsung Technologies America). One was OK. The other one was a fucking psychopath. I'm talking about needlessly and viciously backstabbing all in range. Totally unbelievable. Never seen anything like it, and god help me I hope I never see it again.
Later, I visited their HQ in Korea and met some of their Indian and Korean development teams. They were competent but the work culture was toxic. People were expected to attend 11PM daily review meetings where the issues list was painfully re-read pointlessly and nothing at all was achieved. Koreans were expected to live in numbered company compounds, catch a numbered company bus and ascend to a numbered floor in a numbered company skyscraper after an airport security style physical check. Smoking allowed strictly twice per day in a designated corner of the compound. All movement is tracked. Psychotic Confucian management style. I honestly thought to myself: if this is a vision of the future, I want no part of it.
