What is the largest portfolio you have been responsible for, preferably in a project accounting capacity?

Tell the interviewer about the largest portfolio you have been responsible for in your career, particularly as it pertains to the role you are applying for, in this case project accounting so as to demonstrate you already have the skills required for this role.

If you cannot provide an example in a project accounting capacity, answer by mentioning a portfolio managed in another capacity to prove your skills will be transferable. In this case, provide more than one example to ensure the interviewer will have no doubt you can do the job.
