Camtek interview questions

I has been asked about logical questions, which include probability etc… after that, i have been questioned about technical drawings which include electrical schematics, mechanical schematics and general knowledge about tools

The interview was intended to be 3 hours, they instructed me in advance what to study for the interview. I was interviewed by 2 people from the team. First they asked about me and the things I did in the past as they try to understand in depth the previous jobs I did. Then ask 4 professional questions. Apparently I wasn't good enough, and the interview was shortened to two hours.
