I applied on Gigster and received an automated email shortly after requesting to take an aptitude test (IPRA) and a technical assessment test.
I took the aptitude test despite the fact I don't find it relevant at all in this context because I always found those fun (a sweet 15 minutes). I got ghosted after that. Never had a chance to talk with a recruiter or ask any questions.
I didn't intend to take the 60 minutes technical test because my time, too, matters but seeing hiw this process went, I know anyway that's a company I (or anyone for that matter) should stay away from.
