Talk your way through the problem.

Draw/ write it out: visualize your logic.
BUT "knowing the answer" isn‘t the point, you need to be able to explain it!
Get started; how quickly you can solve matters.
Write out pseudo code/ comments.
State assumptions, think about corner cases.

Skip "administrative" questions; (ask the recruiter)
Show you‘ve done your homework
Know the company
Know the interviewer
