SS&C Software Engineer Internship interview questions

I applied online and was interviewed in Zoom. first round -phone screening interview, second round - 1 hour of technical interview , third round - 3 hours technical interview by 4-5 interviewers. Interview for next round is scheduled after vigorous follow-up mails to the recruiter. After all the interviews and follow up mails, the recruiter did not even take the responsibility of providing the feedback, which is very unprofessional.
