Just be honest and be yourself. If you are applying for a technical position, make sure you well prepare yourself. If you don't know the answer, don't try to guess. Just be honest that you don't know, but try to share some related topic during interview. For example, if they ask you how KU band layout, but your previous experience is focus on KA band support. Tell them and ask for permission to share what you know about KU band instead.
