Battlegrounds In-Game Matchup Selection

Does anyone know how your opponents are selected inside the match (not MMR)? It seems totally random (except no playing the same player twice in a row), but don't know if it's ever been stated. Recently I had match where all 8 players were alive and I played the same player 3 times in 6 matches.  I feel like I sometime go an entire match without ever playing one of the players. The worst is facing AFK on turns 3 and 5. Seems crazy that there is not some sort of round-robin format

It seems truly random to me, aside from not being able to face the same player twice until there's only 2 left. I often notice players being paired up repeatedly (with 1 round intervals), but that's probably me noticing a pattern in a random distribution. 

I do agree that this is one area where randomness might not be the ideal solution compared to other options like facing everyone sequentially or a semi-random system with built-in measures against early repeat matchups. It's lame when you have to face someone who got an early spike while other players get a free ride, and it's more fun if you get to see what everyone else is playing.
