Interrogation

Interrogation was the process of obtaining information.

Upon arriving on a parallel earth, the Third Doctor was mistaken for a spy and interrogated. (TV: Inferno)

The Twelfth Doctor said, "The first rule of being interrogated: you are the only irreplaceable person in the room. Make it work for you. If they threaten you with death, show 'em who's boss: die faster." (TV: Heaven Sent)

Behind the scenes
In real life, interrogation is mostly used by authorities. They often employ the "good cop bad cop" routine to get information out of suspects, with one cop being nice and caring, while the second being gruff and threatening.
