The fact-list reels die because a list has no stake. Nothing is being revealed, so people leave at second two. Game formats work for the same reason in reverse: there is a payoff you have to stay for.
First series I would make: what this job actually pays. One role per reel. Open on the number, as text in the first frame: the role, the pay, how many years in. Then the person, then the route that got them there in one sentence. Last frame, the same job one rung up, so the next reel has a reason to be watched.
Two things that matter more than the format:
- Put the job title on screen in the first frame, not in the caption. Students look up a role by name. That reel has to work as a search result before it works as a recommendation, and the caption does not get indexed the same way.
- Give the comments one question they can answer differently. "Would you take this for that pay?" gets replies. "Five facts about logistics" gets nothing, and replies are what push it past your followers.
Your career ladder instinct is already the right shape, a ladder is a game with a visible next rung. Make the payoff the number rather than the trivia, and hold the template for twelve reels before you judge it. Most pages quit at four, which is before the format has had enough attempts to find the version that works.
