In the first round, I was given a technical test that consisted of 14 questions in total. The questions were spread across various topics, including:

• 10 MCQs on OOPs concepts, primarily based on Java. • 2 MCQs on SQL, covering the basics of database queries. • 1 SQL query where I had to write a query to run a specific function. • 1 DSA problem, which was focused on coding using strings.

The overall difficulty level of the questions was from easy to medium, making it manageable if you have a good grasp of the fundamentals.

In the second round, there was a one-on-one technical interview where I was asked the following questions: • Explain the time complexity of different sorting algorithms. • Discuss the usage of Hashmaps and Dictionaries, and when it is appropriate to use them. • Explain the four pillars of OOP (Abstraction, Encapsulation, Inheritance, Polymorphism) with examples. • Write and explain a query using SQL JOINs, including INNER JOIN and LEFT JOIN. • Why Barclays? What do you think we do here? • How do you manage stress and prepare yourself to work under tight deadlines? I also had to describe a past situation where I faced a similar challenge and how I handled it.

• They asked a few questions related to the projects I mentioned in my resume.
