I think all jobs have that component in many ways, though not all with the veneer of glamour. In my job, it's not doors. It's "I count things".
I'm probably something like a data scientist (my work precedes the popularization of that term) but I'm sort of merging of data/statistical analyst, report writer, occasional programmer, occasional ETL writer etc.
An extremely large amount of my work results in output that is a count of some measure or metric or whatever. It might be something that happened, things happening now, things that might happen. But a lot of it comes down to counts. I recently finished a month-long analysis of 10 years of data to validate potential operational changes. The result? Counts of what happened in the past, counts of what might happen if we make changes.
The list of questions I have to answer, and ask people, is as long as the "doors".
Most jobs are rarely as simple as they appear from the outside. On a novel project, it might take me a week to come up with a single number. I have had a few occasions where I have had to explain in a similar "doors" list why that is often the case. It often ends with me saying something like, "So I can get you a bad number in a day. I can get you something minimally usable in 3 days. Or I can get you the correct answer in a week."
This could be a good way to explain an industry or the roles within a company to newcomers.
