Describe memory BIST architecture, march algorithm, MATS test. String parsing questions to process/filter verilog code encased in ifdef/ifndef. How to set up testbench for, and maximize test coverage for scan debug verification. The engineering manager whom I ate with, asked me for my ethnicity. Although I grew up in California, he kept trying to connect with the interests of his neighbor, who happened to be of the same ethnicity. The questions were along the lines of "My <ethnicity> neighbor, they like to play tennis. Do you like tennis? Do you follow this tennis player from <my country of origin>?"
