Overview
Interviewing for Data Analyst at Barclays
Interviewing for a Data Analyst position at Barclays is a distinct experience from applying to the same role elsewhere. Barclays with 83,000+ employees, has built a structured hiring process that reflects both the demands of the Data Analyst role and the company's own values and culture. The process is designed to assess not just whether you can do the job technically, but whether you'll thrive in Barclays's specific working environment.

You should expect a process that tests your ability to work with tools like SQL (complex queries, optimisation, window functions), Python (pandas, NumPy for data manipulation), Data visualisation (Tableau, Power BI, Looker) in realistic scenarios, not just abstract theory. The interviewers are typically people you'd be working with directly, so the conversation goes both ways — they're evaluating you, but you're also getting a genuine sense of the team and day-to-day work.
Understanding what Barclays values — and how that translates into their interview expectations for a Data Analyst — gives you a significant advantage. This guide breaks down the full process, the specific questions you're likely to face, and how to prepare effectively.
