Qualcomm Logic Design Intern interview questions

This is a on campus interview, two rounds from two different groups, one hour for each. At that time, they asked really quite fundamental questions including timing, energy, FIFO, shift register, FSM in digital and design several small circuits in analog and asked about swing, input output impedance , gain under different circumstance. The digital part went quite well, but I really don't know much about analog at that time.
