There was an exam that covered math, mechanical, software, and electrical engineering. There were many questions. Here are a few: What is the output from this piece of code (this question related to overflow)? What is wrong with this piece of code? Write some code by hand. Draw a free body diagram for a weight being lifted by a lever. Draw an op amp circuit and find its gain. Write the Fourier transform for an op-amp circuit. Calculate the power in a circuit. What is positive feedback? Which is better, negative or positive feedback? Find a derivative. Thermal calculations. How do you calculate RMS voltage? Most of the above questions weren't too difficult, but there were more questions that I don't remember because I probably got them wrong (I wasn't allowed to know the answers).
