I believe the project was either made with a camera spanning a 360 degree vision radius or by animating a 3d space and adding a camera with a script to allow interactivity with a mouse or vr headset.
Assuming the project was made with a 3d camera, probably about 10 to 20 minutes to record and edit. If it is a 3d project made of models it very well could've taken hours to animate each part.
As the number of people who worked on it increase the overall amount of time the project took would significantly go down but I have no way of knowing how many people worked on it.
