45 mins phone interview: task vs function associative arrays packed vs unpacked scoreboard structures `uvm_do sequencer structure coverage: code vs functional functional cov: module and collector number of automatic bins for an int code coverage metrics uvm_object vs uvm_component concurrent vs immediate assertions 5hrs interview: reg model in uvm adapter and predictor scoreboard structure how to use some of the phases exercise on how to verify a DUT that gets data from 2 sensors list of quick questions on systemverilog how to verify req ack interfaces, also which assertions how to verify in a mixed signal enviroment find errors in given code (like missing "virtual" in parent/child sequences, or missing "automatic" in for loop with fork join_none) optimized way to generate Fibonacci's sequence recursive function to generate a given sequence shortest path algorithm: given starting point and destination point in a 2D matrix, get the shortest path from one to the other, including some non valid coordinates what kind of functional coverage I have done, how I've done scoreboards, some other questions about CV experiences
