Interactive missions are quests. You get rewards for your problem solving skills. It involves real thinking not just clicking randomly. Make sure you read the mission text, the answer may be in there. It's not wise to click the same option again and again if you see it fails.
Just try different options and learn from the mistakes.
You can also use a notebook to note the steps that give better rewards and you will do better on the next mission.
More missions on the works.
