My apologies for the delayed response. I hope this has not placed a deficit on your decision making. First of all, Kudos on your recent graduation and beginning a career. I can see your concern, and also want to emphasize your first 5 years is imperative when it comes to building your unique differentiation in the marketplace.
The important thing that I am reading here is you need to see if you are generally interested in the industry, the culture and the possibilities it will provide for you in the future. You also have to honestly ask yourself is this an industry with a sales process and market landscape that fits with a marketing mix I am comfortable developing and possibly disrupting, or will this be a hindrance to your ability to execute the key skills you have acquired over the years.
If I were in your position, I would ask for more then a conviction to grow or budget, when they say do whatever it takes, try to assess the 'scorecard' by which this will be measured. I have developed some key tools that help me position the true influence I can bring to an early stage or high growth organization.
I think there is some positive opportunity for you and since this is the path less travelled, you can find a sweet spot for yourself, and you just have to make sure it aligns with what your passion is and what you are comfortable holding yourself accountable to.
I will be publishing my book, which is exactly the tools and approach to developing a pragmatic approach to aligning sales and marketing with focus on results - you can get a preview here www.playsofprospecting.com
I am more than happy to setup a skype call if you like, you can reach me at asterradalia or on twitter @d_asterra, we can try to carve out 30 minutes if you like and help you position a framework and some methods of evaluating Pros vs Cons. (I am an engineer girl afterall! And everything has a feedback and forecast in some ways :) )
Hope this helps, and enjoy it - you are in a beautiful place and a pivotal moment in your life, so don't put too much pressure on yourself, just try to focus on what matters and how it can carve a path in the long term.
Best, and Good Luck
