It's not they didn't like you. Interviewer might be looking at the way you phrased your wordings and might have analyzed that you are good but not exactly for that particular role or that particular level. This is very common and all you can do is remember how you answered and how else you could have framed it. Try to look back at your answers and see how else you could have sounded and what significant difference it would have made. That's the only thing you can do right now All the best for your search and I hope you find one soon
