Katana Graph interview questions

I applied through LinkedIn and the recruiter reached out to me for a 10-minute chat about my interests and experience. I was invited to the first coding round. The coding round was solving a complex problem in 2-3 parts. It was a simple question. Nothing fancy. The recruiter wasn't very responsive and delayed the response by a week multiple times. I was invited to the onsite consisting of 4 rounds - 2x1 hr, 1x45min, 1x30min. One round had was problem-solving. Another round had a leetcode style question. One round was a presentation from me about a topic of my choice. The last round was a behavioral with the CTO. Most interviewers were pleasant and gave satisfactory answers to my questions on Katana Graph's database. An interviewer just answered my questions in one sentence like I was going to steal their idea and implement a better version of the database. I asked for a feedback and the recruiter did get back to me with a feedback - Everyone thinks you did well but we are not looking for a junior developer. I wonder if this is the standard response because I was interviewing for a junior role lol. None of the interviewers connected with me on LinkedIn even though they were smiling and had a good time interviewing me I wish nothing but the best for the start-up. Congratulations on the recent funding. I hope to see the fastest graph database. Good Luck :) !
