David helped me a lot during the preparation for interview and I see the main impact in two areas.
First, he challenged my application and my story and asked tough questions. That really helped me to think every aspect of my profile deeper and add a new dimension to the story. His approach is really thorough, analytic and no-bullshit.
Second, the mock interview was an experience that was actually harder than the real one. I believe that’s what you need before the real interview because the stress caused by the situation itself will balance it.
Besides David responds really quickly and it’s pleasure to work with him because of his punctuality and accuracy.
P.S. I started to work with David a few days before the application submission date so we had time only for a few last changes.
