Binance Senior Software Engineer interview questions

The interview process was initially fast and HR was prompt in coordinating. The 3rd and 4th rounds of interviews were held together. However, I was given only 1 link for both rounds. I stayed on that link for the 4th round for 20 mins but no interviewer showed up. Hence, I contacted HR but there was no response. HR was on leave; got to know about this through a mutual friend in Binance. The day HR came back, contacted HR via email but no response; till now! To the Interviewer or HR: you cannot leave your candidates out in the dark! All the time spent preparing for interviews is wasted. This is not the way to treat a candidate!
