Flexagon interview questions

I had a call with one of the executives to set up the technical interview. The technical interview was about Vue.js and asked me to do solve a live coding challenge related to Vue. Gave me a pretty easy coding challenge related to Vue which I bombed it completely. I just had to render the width of the html element. I had to mount then select that span element, find the width and then return. Although I bombed that interview because I wasn't prepared much but my experience was very positive due to the hiring manager being very very supportive. He helped me till end to make it through. And then asked me to explain the assessment.
