After the preliminary screening, the time taken to set up an interview may take anywhere from a few days to a few months (assuming they are interested in interviewing you). The interview, for Waterloo based students, will be at whichever location you will be working at, a great chance to take a look at the office culture, and the team that you would be working with as the successful candidate. The interview for this position involved a lot of first-year circuits, with some second-year diode theory.
