Lightspeed Backend Developer II interview questions

The first interview was with someone from HR, where she introduced the company and explained what the company does (I already knew this because I had researched and prepared for the interview). After some time, I received an invitation to participate in a second stage, which would be a more technical interview and a System Design challenge with an Engineering Manager. Unfortunately, during that time I got sick and requested to reschedule, and they were understanding and gave me a new date. The technical interview was also smooth; the interviewer was nice, made me feel comfortable, and I was able to answer all the questions he asked me. The System Design challenge was also straightforward, and the interview lasted approximately 2 hours in total. Afterward, I had the opportunity to ask my own questions. After about a week and a few days, I received an email saying they would not be moving forward with me, and that if I wanted feedback, I could schedule a call. I thought that was unnecessary and just asked them to send the feedback by email instead. A few days later, the same job opening I had applied for reappeared on LinkedIn. Even though I wasn't invited to further stages, and I believe the role wasn't overly demanding in technical terms and I don't know the real reasons that led them to reject me, the process was good overall… I have a slight impression that it had more to do with cultural fit and open-mindedness when making the decision.
