15 Interesting questions in Apple interview!

According to foreign media reports, Google often asks job seekers technical questions when recruiting employees and engineers. Apple, on the other hand, always asks some brain teasers and questions related to hardware specifications, which seems to be more about tapping the creativity of potential employees. Apple's problems are not only aimed at technicians, but also at salespeople and other special people. The following are the most interesting 15 questions provided by GlassDoor, an American website, for Apple to interview candidates:

1 1. How to check the continuity of surface curvature?

Recruitment position: CAD cartographer

Apple drew many prototypes for its own devices, such as iPhone and iPad. Those prototypes need to be tested, so you need to have some people draw prototypes quickly.
