Analog Devices interview questions

Went over my resume and ask detailed questions about the relevant projects that I did. Asked me to draw the high level architecture of the project and explain. Later talked about my research and ask me to describe what I was doing. Had some questions during this part but mainly it's for clarification. Finally talked about what the team is doing.

"Weird" The manger started with asking me if I was expecting more money compared to my previous job. What was my GPA for grad and undergrad (its more than 10 years since I passed undergrad). What was GPA of other students in the class (when I said I didnt know, he said that he still remembers from his times-how weird is that), how many students scored above me in the class etc. This went on for almost 20mins. Then he asked me some basic Digital design questions. 1. Given a 3 input AND gate, design a N input AND gate. 2. Calculate FIFO depth given some parameters 3. Priority Encoder etc Overall, it was a very uncomfortable environment, I just wanted to get out as soon as possible.
