Estimation question

How much bandwidth does the StarWars hologram use?

Practice this question out loud. An AI interviewer asks it, follows up like a real interviewer would, and scores your answer. Type or speak.

What this question tests

Tests estimation skill: breaking an unusual technical scenario into a defensible bandwidth calculation using clearly stated assumptions.

Clarify what the hologram represents technically, likely a real time volumetric video stream rather than a static 3D model.
Estimate the frame resolution and depth data needed for a convincing volumetric effect, stating this as an assumption.
Estimate frame rate needed for smooth motion, typically around 30 frames per second, stated as an assumption.
Multiply data per frame by frame rate to get raw bandwidth, then apply an assumed compression ratio.
Sanity check the final number against known real world video streaming bandwidths, like 4K video.
State clearly that this is a rough order of magnitude estimate, not a precise figure.

States a clear assumption chain: volumetric capture at a resolution comparable to high definition video, depth data roughly doubling raw data needs.
Calculates raw bandwidth before compression, for example resolution times color depth times frame rate, then applies an assumed 10 to 1 compression ratio typical of video codecs.
Sanity checks the final estimate against a known reference point, noting it should land somewhere near or above standard 4K streaming bandwidth given the added depth data.
Clearly flags every assumption as an assumption, since no real specification exists for a fictional hologram.

Giving a single number with no shown reasoning or stated assumptions behind it.
Ignoring that volumetric or depth data roughly doubles bandwidth needs compared to standard flat video.

How would your estimate change if the hologram needed to support multiple viewing angles simultaneously?
What compression assumption did you make, and how confident are you in it?
