Is it OK to ask someone what they do for their job on a first date?

Crucial Questions to Ask When Buying a Business - Viking Mergers &  Acquisitions

Work is an important part of life, so your job will eventually come up. It's not something you need to deep dive into on the first date though. Some people don't have the privilege to say they are proud of their job and it's their passion. Alternate questions that I personally ask and allow me to better understand my date: "What are you passionate about?" and "What do you enjoy doing?" There is nothing necessarily shameful about wanting to be with someone that fits your lifestyle. But leading with that question of "What do you do?" can be a turnoff for some.
