McKinley Rice MERN Stack Developer interview questions

The entire process consists of several rounds: 1. Preliminary round in which (Math/EQ/IQ) questions are asked. 2. Core round in which questions related to the profile are asked. The cut-off for each round is 80% or higher. I scored 60.1% in the first round, so I didn't qualify for the next round.

I have only just given the first round, but the experience was really bad. Aptitude round was really bad, server was down all the time. Wasting my whole day and test was scheduled next day but they were kids level question.
