Dober interview questions

I applied to Spindle (child company of Dober) through LinkedIn, and the hiring manager initially reached out to me through LinkedIn Messenger. She sent a message with a few questions to confirm that I was truly interested in the position, and shortly after that she scheduled a 1:1 interview with me. The interview was supposed to be only 30 minutes long, but it ended up lasting nearly an hour due to how in-depth our conversation became. Following the interview, she sent me two articles and a webinar to review to again make sure I was genuinely interested in the opportunity. It took me almost an hour and forty minutes to go through all of the material. I went above and beyond and wrote a full paragraph summarizing each piece to further prove my commitment and to demonstrate what I had learned. I was then progressed to the next part of the interview process, where two members of her team conducted a detailed interview that required me to answer the same six questions about the last three places I worked. The interview could not have gone better. When I asked both interviewers if they had any hesitations or concerns about my background, they both told me they had none. After all of that, I received nothing but an automated rejection message from LinkedIn informing me that the company was moving forward with other candidates. Given the amount of time, preparation, and effort I invested and the fact that I consistently proved my interest at every stage. Receiving an automated message was extremely disrespectful and unprofessional. At the very least, I deserved a direct response or feedback from the hiring manager I spent so much time engaging with. This experience showed a lack of courtesy and genuine appreciation for candidates, and I would not recommend this company based on how they handled the process.
