TixTrack Web Developer interview questions

I did a total of 4+ hours of interviews with them, 3 of those hours were all repetitive leet code questions. After the final interview, they had the audacity to ask me to come back for an extended interview to solve even more leet code. Keep in mind this is all for a simple web dev role. They kept telling me I was the top candidate and I passed all the interview rounds. A few days after the final interview I got an automated rejection email from HR that sounded like it was written by an AI. Apparently, they picked another candidate. There were no reasons just the generic "you were a strong candidate, but we picked someone else" blah blah. The ones who interviewed me didn't even have the courtesy to reach out in person after the amount of time they wasted me.
