SoFi Backend Developer interview questions

1. HR meeting, (Provider) 2. HackerRank challenge. (Provider) 3. Technical interview. (Provider) 4. Manager interview. (Provider) 5. Technical interview. (SoFi) 6. Manager Interview. (SoFi) Last interview was the worst, Only feedback I had received was "You didn't mention you technical background" How am I supposed to bring up something you haven't asked me about? I just feel like manager didn't prepare the meeting and was just asking random questions with no value to what they wanted to know.
