It was good and very competitive but if we are strong in physics and basics of electronics and mechanics this can be comfortably attend this interview Fluent in English is needed but not must

First interview was with someone representing the entire company. The expectations, like salary and working conditions were asked from you. Also to give some background and your goals. If this interview went well and they thought you could fit the job, you then have a second interview with a manager from the actual facility you are applying. This seemed more to get the range of your experience and if the actual work you were expected to do fit with your idea of what would be conducted. Then a third onsite interview where several members are met and a tour is given. This is similar in structure to the second interview, also very informative and they gently probe your scope of knowledge. The interviews were all made within 3 weeks however to get a reply after the 3rd interview can take a longer time. I am still waiting to hear back after the 3rd interview
