What is the author's style in Monkey Business: Swinging Through the Wall Street Jungle by John Rolfe?

Overall, Monkey Business is a chronological presentation of the first year in the lives of two young associate investment bankers, from recruitment for an earlier summer internship program to the offer of a permanent position and, ultimately, to their "escape" from the crazy and lopsided world into which they had tumbled. Chronology is an essential structure, as it is important for the reader to follow their initial enthusiasm and optimism, followed by questioning, skepticism, and disillusionment, and terminating in their decisions to move on to far more balanced and rewarding career paths.
