There are two ways you can take those kind of requirements:
Negative outlook view: OH GAWD, THOSE ARE UNPOSSIBLE!
Realistic view: They want someone with a ton of experience because they have no idea what they're doing, or the person who does know what they're doing doesn't have time to do a billion different jobs....OPPORTUNITY! CHA-CHING!
It's not about what they want, because most people are busy and would rather have YOU tell them what you can give them. That is the difference between someone with a lot of experience and someone with jack for experience.
10 year experience guy: "Oh yeah I have done this kind of thing before, I did (this this this this and this) but I have been flipping (awesome marketing idea) in my head for awhile, and having studied the history of your company, I think it would work extremely well, and I think so because of my experience with (this). I also have a proven track record of working with people in successful environments, so I can tailor that awesome plan I had to fit in even better with your company, and we can work toward (ongoing realistic goal)."
No experience and doesn't know why he wants to get hired guy: "I went to college, I like your game, and I think you should hire me! I'm young! You tell me what to do and I'll do it!"
^^^^That guy will not get hired because he creates work for people. They have to do his job in order to tell him what to do. No thanks.
Opportunistic new guy: "I will admit, I've not worked professionally in this field for long; however, I believe I am more current on the latest research than someone who has been in the field for ages is, and I always keep current with the effective marketing trends. Here's an example (give example of research you've personally done, showing that you don't need someone to tell you how to work, you can make and find your own work). In addition, I DO have a background in this field, I've done (insert notable accomplishments) and I only see my career expanding from this point. I have worked with people who have been in the industry for years, and I know the processes they go through to do this job. I am very qualified to do the job."
Opportunistic new guy would have an extremely high chance of getting the job. One reason is pay; often people will see "new and awesome" as meaning "getting an awesome person to do a job at a lower cost compared to someone who knows what they're worth." Basically, they are trading their know-how for a better resume. The person hiring is like "Woot, save money and get the same thing," and opportunistic guy says "Woot, I don't need a zillion dollars, but working at this level of marketing would be HUGE for my career going forward, and I can always negotiate a higher pay after I prove I'm worth it."
Pretty much this: You want a good job? Make it easy for someone to hire you. Do their work for them, even during the interview. Volunteer information about yourself, ask them specifics on what they are looking for BEFORE the interview, tailor yourself to fill a role. Do research, work with people in the field (some college professors have been doing their jobs for over 30 years and are crafty SOBs, and many will converse with non-students via email if you're interesting and they get something out of it). Basically, it's not THEIR job to hire you, it's your job to hire yourself, and they just have to sign a few dotted lines to make it official.
Hope this helps you future job hunters.
