The ending of every scene has to be logical; it can’t cheat the readers. They have eagerly read the scene, worrying about a question. So to play fair with them, the conclusion of your scene has to answer the question posed by the goal in the first place.
So if the question was whether the destroyer would sink the sub, the end of the scene has to answer that question. If the question was whether the woman would get the job, the end of the scene has to tell whether she did or didn’t get the job.

A scene starts in one place emotionally and ends in another place emotionally. Starts angry, ends embarrassed. Starts lovestruck, ends disgusted.
