After I applied , they sent me a coding challenge in C#. It was the knapsack problem applied to the blockchain. Don't forget the hash table for dynamic programming, even though it didn't have any effect on the particular weights and values they chose. I was invited to their office. A group of Japanese guys came into the room. They were unable to decipher my strange western resume and asked me questions about it as they tried to skim the freshly printed papers while maintaining an air of authority. They asked why I was interested in their company and how passionate I was about bitcoin. Their mannerisms were offensive and it was clear that they only wanted to see how much I would bow to the heavy vertical authority of a Japanese company. There were no technical questions. The job description was "C# Software Engineer" but they explained that aaaactually there were many different teams and I could choose between backend, front-end, whatever. It is a traditional Japanese company, meaning they will hire anyone then mold them into a particular department. Once you enter enter the company, all your experience gets ignored and you start from the bottom as a disposable foreigner. The job posting was not the job they interviewed me for. Actually, they constantly have the same jobs posted online year after year, probably because of turnover. It's not like one position had suddenly opened up. Just a warm body mill.
