The interview process has four steps: a phone screen with the HR, a phone call with the hiring manager, take-a home design exercise, and a video chat with the team. I was rejected after submitting the design exercise and only getting a generic one-sentence feedback from HR saying "great understanding and approach" but need a "deeper dive into user research and visual designs". The exercise prompt was pretty vague and open-ended, so not sure what exactly would the team consider to be enough research and visual design. Also had no chance to have a dialogue since the company only asked to turn in a PDF report. Design rarely happen in a vacuum, would recommend the company scrap take-home exercise in the future and invite the interviewee to do a 1-hour collaborative exercise with the team or at least provide more detailed feedback. This would be more respectful of the interviewee's time.
