Tradeling Software Engineer interview questions

The interviewers were very friendly, cool and helpful, but one of them was more similar to academic style. 1st round was a deep full screening technical interview, 2nd was a 2hours app implementation with a freedom to use any tool and both rounds were smoothly going. after that, I didn't get any response from the recruiter whether rejected or accepted, however I asked for update and feedback but also no response which is totally unprofessional. "Don't think this bad attitude is still alive except in the dummy companies"
