EE Interview Process For an electronic design engineering position
Schedule • Morning • EE Questions • General Design Process Questions • Lab Session • Software Questions • Afternoon • Behavioral
EE Questions • Design an OPAMP with a gain of +10 • Draw a NPN transistor and label the nodes • Attach a 5V source to the Base and a 1kOhm resistor to the collector and emitter • Analyze this circuit • Replace NPN transistor with a N-Channel MOSFET • Describe different types of MOSFETS and different modes of operation • Analyze this circuit
General Design Process • Have I designed and laid out a PCB before? • Programs used • Where their any layout restrictions to take into account • How did you build the PCB • Environmental check (Lead free?)
Lab Session • Build an OPAMP with a gain of +10 • Build a switch for an LED using a MOSFET, 500 ohm resistor, 5 V source, button press and an LED • Build a circuit that will take a sinusoidal input and give a DC output = to the sinusoids amplitude • Analyzed a simple circuit they had built and point out the flaws (When the board was populated the manufactureput parts on backward and wrong value resistor)
Software Questions • Embedded system level • Logical flow of program(i.e. If/Else) • Different variable and their function (i.e. Don’t use int when you need decimals, use float) • Not syntax oriented
Comp. Arch specific (Dft. Interview) • What is a cache • Different setups for GPIO (High, Low, Tri-State etc…) • Determine bitrates from given information • What is a bootstrapping • List some different setups for MOSFETS and BJT (i.e. Open collector)
