What should you NOT say in a job interview? The first thing that comes to my mind is nothing. You should not say nothing.
If somebody asks you a question and you’re not sure of the answer or all the words just completely left your head, it’s important to acknowledge that, say, ‘oh my goodness, I just forgot that the word I was looking for,’ and then from there, share your thought process, like how you would go about solving the problem.
We’re all human. So it’s just about connecting with the other person, and not feeling bad about not being perfect.
