For the game industry this is practically amazing.

Firstly, for 99% of appointments they usually don't care how good of a developer you are. You may have invented 10 new technologies and have revolutionized the field, if you can't show them a portfolio of games you have shipped then they don't care. They don't hire you for a developer/code role because you're a great developer, they hire you because you've shipped some games before (which is totally a different metric). For whatever reason the whole industry is stuck in this mentality, they can't differentiate between the metrics of appointing a great developer vs trying to find someone that can ship titles.

Asking for expected salary is a pretty quick way to filter because no one ever lists their requirement in their cv. If the job listing included their range then they might have gone with just assuming that the applicants would be within that range, but it doesn't hurt to check.

The test itself is quite easy and straightforward, if anything the real gotchas around it would be to stand out significantly from everyone else.
