Hopper Product Designer interview questions

The process took almost 8 weeks during the summer of 2019 and I had 2 meetings in person with the Lead Designer, 2 calls with HR and Management, 1 design test, and some follow-up emails. Honestly, the design test should be renamed "free consulting work". I felt they give the design test to all candidates even if they already know they will not hire them. Also after I presented the work, the lead designer followed-up with questions by email about the strategy and what I would do if X and Y. Finally after 8 weeks, the recruiting experience has been ended with a very ordinary rejection email from HR. It's fine that I didn't get the job and I have no doubt they found someone who was better. But after such a long process, free work, and meeting 3 times with the same lead designer you expect a personal note from him to close the process and not an HR email that just sounds like a template.
