<human>: Can you condense the text into three sentences or less?

Whe I graduated college with a BS in public relations and advertisement I couldn't find any work. So, I followed advice and networked my ass off. I ended up networking my way to the COO of a retail merchandising company. He found me a position in his company at the bottom of the totem pole making $11 an hour. Not terrible starting off and I'm a firm believer that if you want to move up in a company you have to start at the bottom and "learn to push the wheel barrow". 

After a couple of weeks, the COO contacted me and was checking on how things were going. He told me to keep my head up and stay focused because they were prepping me for my boss' position. He said it could be as early as January. My boss is 62 and could retire at any time... Or he could stay in for another 3 years leaving me at the bottom of the totem pole making 11 bucks an hour.

Since I've been hired, I've received a call from a huge company i applied for a couple months ago telling me that they're very interested in me and they have to positions available that they want me to fill. One is customer service and the other is in their marketing department. I've scheduled an appointment to meet with them tomorrow (since I'm out of work until January). 

If they offer me a position, should I take it? I know being in a company where you have the COO as a mentor is idea but I'm running the risk of being stuck in a position I don't want to be in for three years.

I'm sure I've left a lot of details out so feel free to ask questions if it will help you give me good advice.
<bot>: I have a part time job where they're prepping me to be the operations manager but it could be now or in 3 years. I've been offered a full time job in the marketing dept by another company.
