It appears that what will be most useful here is identifying a general process for finding out what each occupation really entails. If you know someone who does it, obviously that’s a good source. Will the internet serve? I googled “life as an accountant” & straight away got an article “Here’s What An Accountant Does All Day,” where an accountant describes her typical day. Also, I remember Stud Terkel’s great book “Working: People Talk About What They Do All Day and How They Feel About What They Do” wherein individuals in various occupations describe their work; a 1997 edition is available. Unfortunately, there is a lot of dialogue one encounters about what an occupation entails from people who haven’t done it (school guidance counselors and occupations profiles websites come to mind), and this material can be incomplete or wrong. I haven’t yet succeeded in finding an internet version of Studs Terkel’s book (personal accounts, with an aim to cover a wide array of occupations), but it would be easy to create.
