When asked about a specific technical term, the Tesla interviewer seeks to understand how in-depth your knowledge is and whether you have the expertise required for this position. While it is impossible to be knowledgeable about all the technical terms used in any job, you should be familiar with most of them and be able to discuss them. If you aren't, admit this to the interviewer and then describe how you would go about learning about the technology.

William Swansen

"RISC, which stands for reduced instruction set computer, is an architecture which uses a smaller optimized set of instructions to operate. This is in contrast to more complex and highly specialized sets of instructions found in other computers or processors. While this latter group of computers can perform more functions, the RISC architecture device is designed for a very specific functionality. These are common in dedicated devices or appliances."
