I don't work for Z2I (I run Space Bandits) but that's a good point and definitely would have been worth including in the interview.

I found this explanation in their payload user guide of an example flight profile (excerpt):

The first stage burns for 110 seconds, upon which the vehicle reaches an altitude of 80 km and an inertial speed of 2.3 km/s. After ejecting the first stage, the vehicle reaches 400 km and 4.4 km/s in 230 seconds. Upon third and final stage separation, the third stage performs multiple firings, the first one lasting 340 seconds and reaching 600 km of altitude while still slightly below the target orbital speed. Then, after coasting and later finalizing the orbit, the payload is released.

Thanks for raising that :)
