Solaris Group Software Engineer interview questions

1. Introductory call with HR. The interviewer was a good and friendly person. 2. Tech interview with some standard questions related to Golang and software development. 3. Three back to back interviews. The first was with the hiring manager and product owner. The second was with HR(behavioral interview). Third was related to design & architecture. During the last round, my internet connection was very poor and so was Interviewer's English. I had difficulty in understanding the question. We couldn't finish the interview properly and it was decided it will be rescheduled. But after a few days, I received a mail saying that they are moving forward with other candidates. I felt it was quite unfair to the candidate.
