I'm not a job seeker, but I paid for this thinking it was an investment for the future. I hesitated quite a bit because of the high price, but I bought it with the mindset that it's better to quickly learn the know-how from an expert than to worry about what the right answer is on my own. The lecture explains things at a more beginner-friendly level than I expected. It's the perfect level for me to have seen when I was a newbie. I don't know why there weren't lectures like this when I was looking for a job.
