Met with the HR department managers at the career fair at school. Was called in for an interview a couple weeks later. Was informed that the interview would take approximately 4 hours. First there was a briefing and welcoming to Western Digital and what kind of benefits you'd receive if you were to be hired, it was very light and funny even though everyone was in a serious mood. Then you'd be dismissed one by one to your exam/interview room where you first have to complete an hour long exam that test you on the basics of electrical & computer engineering. (Circuits, networks, R, RL, RC, RLC, MOSFETs, CMOS, BJTs, programming, loops, scripting, function calls, computer architecture). After that, there are 4 engineers from different departments that comes in to interview you and ask you technical questions. It depends on the engineer's skills and if they match yours, then they'll ask you technical questions. Try to do your best on the board. Sometimes engineers will ask you behavioral questions.
