Maxis Data Engineer interview questions

I received an interview invite and asked to come for a group interview. Interview was alright, not much technical questions were asked. It was sort of a general interview where they asked about my profile, experience and explained me about the job role and their requirement. After following up, I got a rejected email from them. I am fine with their process, only thing i did not like is their feedback. They should have provided the detailed feedback why they did not proceed further with my application.
