Intel Corporation Full Stack Developer interview questions

An interview was scheduled where the Hiring manager called and asked me to create a small application and deploy it on github. I cleared this round. In the second round was a coding interview where a simple question was asked and I provided an efficient and logical solution. The interview was taken by someone who had joined intel recently. I was rejected even though I solved the coding problem. It was a clear waste of time. Had a very bad interview experience.

Two rounds. In the first round, talk about background information and some behavior questions. In the second round, talk with three engineers in the team. Questions includes html, css, javascript, coding, testing, system architecture, etc.
