Easiest bit shifts + addition. There are indeed better algorithms (Karatsuba, Tom-Cook), but not likely to write an implementation in 10 minutes or such.

Hey! Thanks for sharing your experience. I have this interview at the location, can you please tell more about the onsite questions? It will be great if you could kindly tell about the questions focusing on coding(was it all in C?), DSP, image processing and ML.
