Is this how the home buying process is supposed to go?

Me

Back in October we started our search to purchase our first home. Since that time our realtor has not initiated showing us any homes. We’ve found places through Zillow and asked him to show us, which he has with some of them. The whole time we’re looking at these houses he’s on his phone and doesn’t really talk to us much. Other times we’ll text him about a house we’re curious about and he won’t text us back until the next day and say there are already multiple offers on it. I don’t understand and I didn’t expect it to be like this. The thing is, this realtor has years of practice, has hundreds of 5 stars reviews, and is the BOSS of a major real estate chain. Is this really just how searching for a home is? Was I just naive?
