Fivetran Senior Software Development Engineer In Test interview questions

The first round was a HackerRank coding challenge. The second round was with a QA manager via video call in which I was asked two simple coding questions and about my current job and the challenges I've faced in QA and engineering processes. The third round was with a person from the engineering team. I was asked similar questions regarding the challenges I've faced with engineering processes and how to solve them. Later I was asked two coding questions related to arrays and lists. The interviewer had poor internet connection and kept dropping off frequently. But I didn't hear from the HR about the results of the interview despite requesting the same via email and phone calls. Probably the company communicates well with those who get selected but doesn't care much about those who don't.
