I went through an interview with HR where we discussed general things about where I currently work and when I can start then I went on to take a mechanical aptitude test. After passing the aptitude test I went on to an interview with one site supervisor which was more technical where I was asked a few questions like do I know what a torque wrench is or an oscillometer is. After this I went on to a panel interview with a Site Supervisor and Site Technical Lead, along with the Associate Director of Field Services which had more technical questions like how does light bend in different types of lenses or mirrors. Then I went on to an interview with the Senior VP of Engineering from japan and the Associate Director of Engineering in Japanese. This also consisted of different technical questions and it was pretty much a test of my Japanese. After this interview I was told by the HR that I was to receive an offer and to wait till next week for them to send it to me. Then I was told I was going to do an interview with the CEO of Nikon Precision for a final interview where they will explain my role there at Nikon. I then received a phone call from HR that they will go in a different direction since my Japanese wasn't up to the level needed which I found was extremely unprofessional since the HR rep had told me they would send me an offer.
