Broadcom FW/DSP Intern interview questions

Phone screening by a member of the team looking for an intern, briefly covered my resume but no technical questions. HR contacted to schedule an interview after initial phone screen. The interview was with 5 individuals for 45 minutes each, 4 asked technical questions while only one focused more on fit/personality/past experiences. Questions: -Binary tree -what virtual is used for in C++ -function to get n LSBs -search header file for version number -static/global scope -write the code for any sorting algorithm you want
