I applied through college or university. I interviewed at Analog Devices (Norwood, MA) in Mar 2015
Interview
Had a 3hour interview with different people. One round was on programming. The other was some basic questions on circuits. Programming round was flexible and you could program in whicherver language you preferred
Interview questions [1]
Question 1
They asked about cache memory, interrupts and other mcu related stuff. Not any questions on DSP. Little bit of VLSI can also be useful
