Checkatrade interview questions

First stage, HR interview. Average interview. Second Stage Hiring Manager. I found the experience a bit strange but it is difficult to rate the whole experience. The conversation began with an introduction, and soon after, I was given an exercise. I received a brief context about a product and was asked to answer a few questions, which we did not get a chance to discuss due to time constrains.

3 stages, final round on site where there was a small case study to deliver.Intro call was done by a recruiter where normal screen questions were asked which i answered and got good feedback.
