I was a busy season (December-March) assurance intern with RSM. Training was held in Chicago, Illinois for a week with all the interns for the firm. During the day you have "class" with about 20 other interns and two instructors that are auditors with RSM. At the beginning the basics of assurance and the programs you will be using during your internship are covered. The rest of the week is spent working through three separate sections of an audit with the other interns at your table. During these mock audits you will be following steps and information from the training manual and will be able to ask questions. The lessons are broken up throughout the day either by your instructors with small games, snacks, lunch and one day there is a speaker that focuses on working in a professional environment. Class is from 8am to 5pm each day and two nights there are events but otherwise you are encouraged to interact with your new connections. The two planned events are a social/cocktail hour on the first night on training and the second is a dinner and game type activity that is put on by a local charity.
In addition to the specific training week you receive technology training when you return to your local office. This consist of learning/refreshing on excel (you will walk through mock examples of the common functions you will use in your auditing) and learning IDEA (a program that can aid in audits).
I found that the training week was very helpful in becoming familiar with the software RSM uses and navigating through it. The mock audits that we conducted gave be a better understanding of what to expect and a foundation to start with. Ultimately I learned the most once I started on my first client and was able to work through my assignments and ask questions.
For a busy season intern, shortly after a couple day in office orientation there will be a week long national training at where you are taught the basics of the work you will be performing in your internship. It is a great opportunity to meet other interns from across the firm and well as develop a solid foundation of knowledge to carry into your internship. Depending on your industry focus, you will have more specific trainings as well to help you get acclimated to the work you will be doing.
