I got the call for the opportunity on Go, though I don't know Go & never worked on this. But they were ready to train the people on Go lang. So I agreed to have the discussions. It was over BlueJeans. It took 2 hrs & the interviewer was patient enough to listen to the approach I was taking to solve the problem. So experience was ok. But I have to say that interviewers in such organisations are themselves not above average but they pretend themselves to be very smart after referring the interview questions from the internet. I can't understand if interviewer can't find the sensible questions to discuss on from his/her work life then how these people can expect the candidates to give the prefect answers in those few minutes.
