There was a phone screen in the beginning, then an on-site interview with four people, including the manager.

Consider 4 components of a color where:

unsigned char red   = 0x10;
unsigned char green = 0xFF;
unsigned char blue  = 0x0F;
unsigned char alpha = 0x44;

Generate a packed color ARGB which is a 32-bit integer such that A is in the MSB of ARGB, followed by red, green, and blue.

| A | R | G | B |
