On the other hand, would you really accept an offer without having at least met the people you'd have to work with? Especially if you have to move across the country?
This might just be me, but video chat doesn't really do it. You don't get an idea of the building, bathrooms, cafeteria, and the general idea of how often your coworkers bathe.
All of these can be pretty important to my general mental health.
I wouldn't, no. But in the 2 situations where I have been asked to fly to a company I said I would be happy to once I had an offer of employment. Both did remote interviews and extended an offer.
