Could you please let me know if there “are” any writing “mistakes” in the below article: :) I used to work for xx bank as a Retail Banking Consultant. My main job “was” problem-solving for customers and selling financial products. **Every time, before I served the customers, I “would need to” confirm and update their details, such as physical addresses, phone numbers, “and” emails. After “serving” the customers, I also “needed” to update their profiles with our conversation and newly completed transactions, which”included” home-loan, insurance, “and” credit-card “limits”. I understand it is critical for the bank to collect and update their customers’ data. From analyzing its database, a bank “can not only” get more in-depth customers insight and offer better service and products, but it “can also” predict the market trend and the country’s future economy. I “have” never worked in the Data/Business Analysis field. Still, I am always curious to know how an analyst collects, “filters” and “analyses” the database and then makes a valuable and viable business recommendation. **Your sentence isn’t incorrect, but would (in my opinion) be better structured as: “On every occasion prior to serving the customers, I would be required to confirm and update their details, such as physical addresses, phone numbers, and emails.”
