This is every remote meeting in my experience, regardless of technology. The first 5-10 minutes or longer are spent getting everyone online, seeing and hearing each other, resolving echos and feedback, etc.
One of my best video conferencing purchases was a Jabra speaker/microphone that has a ring of LED's that tells me when it's muted. It's not always clear in a UI whether the mic is muted or not "The mute icon is bold white, does that mean it's muted or does that mean I need to click to mute?", but I can tell from the red LED's on my speaker, and it has a mute button on it so I always know how to mute.
Chime tried to be the internal Slack equivalent for an embarrassingly long time. Slack has only been used for a handful of months, and some (frustratingly) have not yet switched over.
Used it for an interview and was pretty disappointed in the video quality. Rather choppy and audio felt really compressed, but that might just be on the far end.
Google Meet, at least after their redesign, works really smoothly for me. We use it for our day-to-day meetings at work with non-government clients. Pre-redesign I really didn't care for Meet though.
