Ubiquiti Front End Developer interview questions

Got an email from HR saying that I was selected to move forward and that I was going to get a test of my knowledge of coding. The "test" is what I could only describe as a 25-30+ hr project that you are expected to do in a week, in your free time for free. The difficulty of the interview didn't come from any advance coding or feature demands but the time commitment required. You also don't speak to any humans during the process which never bodes well. It also was damning that the other reviews here mentioned getting ghosted after completing the project.

Very unprofessional, they have you do a call with the team and then send you a coding challenge where you have to make a whole web application that took me a week working full time. During this process they're super communicative but after a week or so after I submitted it they ghosted me. Totally understand if the work wasn't up to standard and they sent a rejection email soon after but it felt disrespectful to ghost someone instead of just telling them especially after making them put in so much time.
