1st call with hr, 2d call with tech devs, Was easy task for solving react problem, why especially components are re-rendered. And description was pletty clever at the beginning, The problem appeared when I took a look into code. It was garbage, so I was trying to listen devs and understanding unpleasant code. In addition, they provided as a hint some bad ideas, which led me astray. I started nervous and was thinking maybe the problem is me. However, after the interview, I have calmed down and solved it by myself in 3 min. What i would recommend: don't listen to dev-interviews for a propmts, just handle it by yourself. It's really easy.
