Do you have any experience using SQL?
The interviewer may ask you this question because account support representatives at Stripe frequently have to leverage data to make decisions and to get to the root cause of client issues. Experience with SQL is considered a big plus. Prior to the interview, brush up on what SQL is so you can define it for the interviewer. If you have any experience in this area, talk about it. If not, discuss any interest and plans you have to learn more about SQL in the future.
"To start, SQL stands for Structured Query Language. It's a type of programming language that is used to retrieve information from databases. Technically, it's called a query language. While I am analytical and tech-savvy, I currently lack hands-on experience using SQL. I plan to earn a SQL certification online in the near future, however, because I recognize how helpful it will be to understand this programming language when I'm working with Stripe customers. In the meantime, I'm confident that I will still be very effective in helping customers by actively listening to them, identifying their problem(s), and using data and other resources to determine how to best help them."
