Position2 Analyst interview questions

Mind Boggling experience received an email from the company, was interviewed, later was asked to recommend changes to a specific website as an assignment. Completed the assignment and received an email after one month requesting to provide verbal explanation over video call. After providing the verbal explanation was asked to send a detailed PowerPoint presentation for the recommendation, That is when I noticed that all the recommendations that I had provided over a month back were already implemented and they just wanted to get more information. the only thing that annoys me is the interview process and the kind of scams that they do without hiring someone.
