I was brought in for an onsite screening interview. All of the prep material that was sent to me emphasized the importance of creating a conversation with the interviewer, which I agree with.

However, during the interview, my interviewer told me the problem to solve and then went completely silent. They only answered "yes" or "no" to my questions about the problem.

I get that there's less to talk about during a screening interview, but this approach came across as extremely unfriendly. It probably resulted in wasted time, as I just talked my way through the problem to no particular end.
