RUBRIC – INFORMATIONAL INTERVIEW PAPER 1. First, please read the section in the Syllabus concerning this project. 2. There is no particular stylebook required for this paper. Of course, always use good grammar, spell correctly and, if you do cite a source outside of the interview, please indicate in an intelligible cite (again, no particular stylebook need be followed) to the reader, so he is able to locate the source you cite.

3. Usually, the most common question students have about the project is: What kind of Format do you want? Let’s try to make this simple. There will be basically only two ways to write the paper: · The first way to format the paper would be to just write a seamless narrative with an Introduction, Body, and Conclusion. That is, after the interview, assimilate and digest all your notes, the questions you asked, and answers you received into a story. · The second way to format the paper is where the student sets-out questions asked, or, some other logical organizing category.

With this second kind of formatting, there is still an Introduction, Body, and a Conclusion, as with the first type of format. Remember: the whole point of this project is to finally to make this valuable information your own. That is, we don’t want a transcript. The reader wants to see if you have digested and assimilated the answers from the interview thoroughly enough so that you can paraphrase – put into your own words – what the interview told you. Quotations that really stand out, sure, why not; but, predominately, show the reader that you have run all this wisdom you have gained through your own head.

Another important point about this second format where the questions are set-out explicitly and then the answer, paraphrased: if you do it this way, for each question/answer set-out, before you move on to the next, it is critical that you give some analysis/commentary/meditation, etc., on what you learned from that particular answer. For example, can you show the reader that you are making a logical connection between what was answered and something else that was said by the interviewee elsewhere in the interview; or, is there some connection between the answer and what you’ve learned in any of your classes taken at Chico State; or, what about any connection with your life experience? If nothing else, perhaps the answer that the interviewee gave was not quite correct, and why not!?

This would certainly show the reader you are not just taking face value what was said to you, but that you are doing research on the information provided and comparing/contrasting it with what you’ve learned in class and life, or, your own view of the matter. 4. Think hard about who you would like to interview. Family and friends sometimes can help with introductions. If not, no sweat – start making the contact yourself.

Be persistent, kind and polite. Part of this assignment is trying to learn how to get to people who have the wisdom to share with you and the authority to make decisions. Don’t take it personally if you are not able to get ‘Fish A’ on the hook…people are busy. Note, however, even if you wind-up interviewing ‘Fish B’ for the class, maybe ‘Fish A’ will go for an interview next year! In other words, you won’t be able to use the interview for this class, but so what?

Next year when you finally do the interview you will have made the contact and learned all that great stuff. All this is to say: you can (and really should) use this informational interview tool throughout your career. 5. Note, that some students may already have a career in mind; others not. I know I didn’t know.

Either way, informational interviews are very helpful (for example, just learning that you definitely do NOT want to go into a particular field will have saved you a lot of time, money, and struggle). 6. Please hand-in to the instructor some beginning legal (approximately 10 questions) and some beginning business questions (approximately 10 questions) that you think will be relevant and engaging for the interviewee. And, on the same page, please let the instructor know who you are going to interview. IT TAKES TIME TO SECURE A GOOD INTERVIEW, PLEASE GET STARTED RIGHT AWAY.

7. Between now and the time of your interview, the key is to REFINE, REFINE, REFINE your questions!! The instructor is here to help if you seek him out in office hours. The essence of this project, though, is the gradual development in the student’s own mind of the formulating question, as he/she tries to make conscious to himself/herself: ‘What exactly do I want to learn here? And, why?

Accordingly with my own aspirations in life, how can this person (the interviewee) help me to understand what I want or need to know? And, as to the questions I pose to the interviewee: Are they relevant to her/her job description? Will they likely know how to answer the question? Does it have anything to do with what they do for a living, or where their interests lie?’ 8. RESEARCH, RESEARCH, RESEARCH THE INTERVIEWEE AND HIS/HER ORGANIZATION.

This is vitally important: You cannot possibly know how to construct relevant and engaging questions for the interviewee, if you do not know a great deal about them and their organizations! 9. And, after the interview, during the time you are digesting all the valuable information you obtained by way of the interview….RESEARCH, RESEARCH, AND RESEARCH some more, the answers given you, before you finally write-up your paper. 10. There will be a lot more questions.

Come and see me. That is why I’m here. ----------------- Cole Erny 4/17/2021 Bettencourt Informational Interview For my informational interview, I interviewed Abel Peter, a CPA certified accountant. He was a long time family friend who showed me the inner workings of his field. We have known Peter for years, and before COVID-19 I was even able to go to his office to see his job on a day to day basis. As a business marketing major, I strive to attain his current status.

Even though my major was marketing, he also studied marketing with a focus in accounting. He agreed to do the interview when time allowed, and we did a live session on zoom as opposed to a phone call. When asking him about his path to being a CPA, I learned that he gained his marketing degree with a focus in accounting, and later went back to school to study for his accounting degree. He spent a total of 6 years at UC Berkeley to gain two degrees. Mr.

Peter made me question my own major, and whether I should switch to accounting myself. When I asked Mr. Peter about the prospect of me switching my major, he told me that he himself wasn’t entirely sure what he wanted to do either. This made me much more assured, hearing from a successful man that he also wasn't entirely sure what he wanted to do when he was in college. I then moved more into his business, and asked him the steps that he took in order to gain his CPA.

Mr. Peter told me about not one, but two tests. The Uniform CPA Exam and the Professional Ethics exam for CPAs were required for him to gain this license. He also told me about the year of experience he needed under his mentor, John Gray. Mr.

Peter completely understood the requirement, noting that he gained extremely valuable experience during this time. Furthermore, he concluded my question by saying he never would have learned some of the things his mentor taught him in school. The next question I asked Mr. Peter was about the services his company provides to the market. He told me that one of the most important services is the advice and recommendations he gives to people who use his services.

He can mostly predict markets, allowing him to give recommendations to his clients on what moves to make in the business market. He also provides services to see if a company will break even depending on changes they make in their business strategy. Mr. Peter also said that he had been used by future business owners to see if a business idea is profitable and attainable

Informational Interview with Abel Peter, CPA: Insights into the Accounting Profession

Introduction

Informational interviews are invaluable tools for gaining insights into specific careers and industries by learning from seasoned professionals. For this assignment, I had the opportunity to interview Abel Peter, a Certified Public Accountant (CPA) and a long-time family friend. His extensive experience and expertise in accounting and finance provided me with a solid understanding of the profession, the educational pathways necessary to enter it, and the daily challenges CPAs face in their careers. This paper will summarize the key points gleaned from the interview and discuss their implications for my career development.

Path to Becoming a CPA

Abel Peter's journey to becoming a CPA is both inspiring and enlightening. He began his academic journey at the University of California, Berkeley, where he pursued a degree in marketing with a focus on accounting. After graduating, he recognized the importance of a specialized skill set in the business realm, prompting him to further his education by studying for a second degree in accounting. In total, he spent six years in higher education, highlighting the commitment required to excel in this competitive field.
During the interview, Peter shared that the path to becoming a CPA is not straightforward. The rigorous process includes passing two significant examinations: the Uniform CPA Exam and the Professional Ethics exam. Additionally, candidates must complete one year of relevant work experience under a licensed CPA's supervision. Peter emphasized that this practical experience is crucial; the knowledge and skills acquired under a mentor's guidance often far exceed what is learned in formal coursework. This realization resonated with me, as it underscored the importance of seeking mentorship and real-world experience in any field.

Career Guidance and Self-Discovery

One particularly illuminating part of the interview was when I inquired about the prospect of switching my major from marketing to accounting. Peter candidly shared that he, too, experienced uncertainty about his career path during his college years. His acknowledgement of this uncertainty helped ease my concerns about my own academic journey. He emphasized the importance of pursuing what interests you, suggesting that exploration is a critical part of self-discovery. This advice has encouraged me to reflect on my aspirations and consider how my interests align with my career goals.

Services Offered by CPAs

Abel Peter elaborated on the range of services offered by his accounting firm. Beyond traditional tax preparation, CPAs provide strategic advice, financial forecasting, and market predictions, which are essential for business growth. As a CPA, he plays a critical role in guiding clients through complex financial landscapes, allowing them to make informed decisions based on reliable data and projections.
One of the most significant services Peter mentioned was advising businesses on their financial strategies to determine break-even points and profitability. This analytical approach is vital for startups and established companies alike, as it helps them assess their financial health against potential changes in their business operations. The ability to predict market trends and guide clients accordingly is invaluable, especially in a rapidly evolving business environment.

Engagement with Clients and Ethical Standards

Moreover, Peter discussed the importance of maintaining strong relationships with clients and understanding their unique needs. Effective communication is vital in building trust and delivering tailored solutions. By actively engaging with clients, CPAs can provide personalized recommendations that align with their specific financial goals.
Ethics in accounting also emerged as a crucial topic during our discussion. Peter articulated that maintaining integrity and adherence to ethical principles is essential for the profession. As a CPA, he is not only responsible for managing financial information but also for upholding the trust placed in him by clients and the community. This adherence to ethical standards reinforces the reputation of the accounting profession and cultivates long-term client relationships.

Conclusion

The informational interview with Abel Peter provided profound insights into the accounting profession, emphasizing the necessity of academic rigor, practical experience, and ethical standards. His journey from a marketing student to a successful CPA highlights the importance of adaptability and self-discovery in one's career path.
As I contemplate my future, Peter's advice encourages me to remain open to exploring different opportunities, understanding that every experience, whether related directly to my major or not, contributes to my professional growth. The insights gained from this interview have enriched my understanding of the accounting field and reinforced the idea that success in any profession hinges on a combination of education, real-world experience, personal interest, and ethical integrity.
