Leica Microsystems interview questions

Initially consultant kept calling again and again daily and kept threatening that as if it's a Google interview that you should go without fail. Go on time. They don't have time. They can't come on weekends. Like as if it's my luck that they have called me for the interview. One guy came for interviewing. He was coming inside and didn't even shake his hand with no basic manners. His face and his reactions were such annoying things to see. He asked to give a short brief about myself. When I kept saying only he said ok that's all enough, now I will give a question paper, you need to clear this for further discussion. After answering he started asking questions about my answers. He was not convinced.
