Had to go through 4 different rounds of interviews. Was a positive vibe and environment but with some tough questions to answer on the spot, so preparation is key. For some questions some help was offered if the answer didnt come right away.

1st with HR in Japan, 2nd with position's manager in Japan, and 3rd with counter partner from US, and 4th with position's manager in Japan again. Results takes about a week each time.
