Broadcom interview questions

Contacted by Hiring Manager and had an informal phone conversation initially to gauge interest from both sides. Phone interview with a Design Engineer within the group a couple days later which asked basic questions about IC design and circuits (RLC circuits, matching, GBW, amplifiers, etc.). Brought on-site and had multiple 1:1 interviews during the day as well as one 2:1 interview. All asked questions about basic analog and RF IC design as well as things about my resume. Tried to take things from my resume and ask very specific details about everything on it and would not accept a general answer. Interview ended with Design Manager and another round of questions about amplifier design with vague/general questions and expecting very specific answers without giving enough information. Interview lasted a total of about 4 hours. Never heard back from them.
