As a student who is undertaking a course in accountancy, auditing, business finance and other related fields, you are likely to benefit a great deal from an internship at an audit firm. The few internship opportunities at the top audit firms tend to attract numerous applications: meaning that there is a great deal of competition for such opportunities. But even before you get to the stage where you have to think about the competition for the audit internship opportunities, you have to figure out how to apply for the internships first. It is only after entering an application that your application will be considered alongside those of others (hence the competition).
Now the top audit firms tend to have ‘careers’ pages on their websites, where open positions, including internship/college positions are advertised. If you find internships advertised at such pages, you can proceed to enter applications. Besides the audit firms, you also have to appreciate that all other types of organizations tend to have internal audit departments, where you can get internship opportunities as well. If you play your cards well enough, you can even land a well-paid internship. That would mean, for instance, being able to visit a HR portal (such as the one accessible through the greatpeople.me login page), and actually viewing a paycheck earned as an intern.
Another approach you can use, while trying to get an audit internship is that of simply making an unsolicited application. You have little (if anything) to lose, and with some luck, you may just land an internship opportunity this way.
Yet another approach you can use, while trying to get an audit internship is that of networking with the people who work in the audit firms (and in the internal audit departments of various organizations). You can ask them about internship opportunities available in their organizations or in their audit firms. Again, with some luck, you may be able to land a lucrative internship opportunity this way. In any event, there is very little for you to lose by taking the initiative to network with these people.
