I went through three technical interviews, each conducted by a team lead from a different formal verification team.

In the first interview, I was asked to implement a waveform edge detector using flip-flops and logic gates, then write SystemVerilog assertions to cover the design. I was also asked to write a function in SystemVerilog.

In the second interview, I was asked a logic puzzle, followed by a coding problem to solve in pseudocode.

The third interview included a logic question, an implementation of multiplication using only ADD and JUMP in assembly, and then the implementation of a digital component using logic gates.

The process was professional and challenging, with a strong focus on both practical coding and logical thinking.

Q: How would you implement a multiplication function using only ADD and JUMP instructions in assembly?
