Entrevista de Product Data Analyst

-San Francisco, CA

BlackRock

Most of the questions were regarding my work experience so far. And a few logic questions like what is the angle between the hours hand and minutes hand when the time is 3:15; How do I identify which switch corresponds to which light bulb when the switches are in one room and the bulbs are in another and given that I can enter the room with bulbs only once.

Because hours hand will only stay at 3 when minutes hand points to 12. So when minutes hand points to 15, and there are 60 minutes per round, the angle from 3 - 4 is (1/12)*360 = 30, then the angle between hours hand and minutes hand is is (15/60)*30 = 7.5
