Overall, the interview went positively. The motivation for working for the company, previous experience and expectations were discussed. To progress to the next stage you have to take the candidate quiz, in which in addition to the logic, search for the unknowns and solving equations, there are also problems with two unknowns, which are difficult to solve without graphing. I still don't understand how this helps to solve problems in partner development, maybe I'm not smart enough to do it.
