Don't write on the whiteboard
Sorry OP, I realize that you're just trying to be helpful sharing what's worked for you and I appreciate that, but frankly, I hate posts like this...I think the best preparation for any interview is to simply get good at what you do. All the rest is window dressing that distracts from that goal.Every minute spent practicing interviewing would be better spent building stuff. The natural byproduct of this will be exercising those skills that will be evaluated.What you're proposing is unnatural and unnecessary. You're focusing on the details of the process instead of the real issue of knowing your stuff.Good interviewers won't care if you're fundamentally solid but a little light on the presentation side. And they won't be fooled by a great presenter who is weak under the hood. Sure, you may fool a weak interviewer, but what does that say about the company you may be joining?We all want to be solid in both fundamentals and presentation, but I prefer to focus my limited resources on getting better than I am, not appearing to be better. Best to just be good, be yourself, and trust that it will show naturally, no matter how you are evaluated.
