Initially, HR emailed to set up an initial screening. The phone screening consisted of background questions and questions about my education.

A technical interview followed about a week later. The process felt a bit strange because the person who originally contacted me (HR) either moved to another position or left the company, resulting in me being passed around to three different HR representatives throughout the process.

Write a function with integer input which returns an integer having been flipped around in the binary sense.

Example: Given 3, it should be turned into 0000 0011. Then, it is flipped to 1100 0000, and the function should return 64 + 128 = 192.

I commented that this was easily done via bitwise manipulations, but I have not done those in a while, so I wrote a program out in C to do it manually.
