I got the job of my dream at the company of my dream by sending an 1 min improvised introduction video + a lengthy cover letter answering all the questions in the job description.

That's the first time I ever tried it and will likely be the last one (since i don't want to go to a different company).

Caveat: this will prob work for a smaller company, not Google-like.
