Multiable interview questions

Before interview, there was two exams each 20 minutes long. First one was about some high school math, and the second one was about AI related questions. The first exam has not sufficient time; therefore, has to solve the questions really quick.

Ability test, in a room with no person. Fill a form with personal information then complete 2 tasks 1: 25 Simple algebra MC that in 30 mins. Calculator is offered but it is consfusing so better bring your own. Better to approximate the answer than to actually calculate it. 2: 30mins translate a Chinese text to English. The text is kind of an instruction. If the interviwer is on site, interview follows. Mostly chit chating without in deep technical dicussion or preculiar question.
