Does rank matter in sponsorship for DNS?

So I had given my Anglo written on 12 July and my SISL on 28 aug. Anglo interview dates are not out yet for mine but i had my SISL interview on 10th of September. Long story short they only asked me 3 non tech questions and said “Yeah you can leave now”. I feel like i didn’t give my best to answer their questions and maybe my rank was a turn off. Coming to my qualifications my PCM is 89%, English 94 and IMU rank is 11928. I have my Anglo interview coming up so i need advice on how to clear it.
