1. HR interview related to standard job experience, why Barclays, why are you leaving current company, salary expectations, etc

2. Technical interview over the phone.

3. Face to face interview with 4-5 interviewers.

It's absolutely ridiculous that I was informed of being interviewed for one position however was interviewed for some other position. Also, they had provided me with the interviewer information however none of them were correct and there were entirely new guys with new names in interview. They stated there was control interview and behavioral interview but everyone who interviewed me only asked me technical questions. Very strange.

Phone interview questions:

1. Difference between sprint backlog vs product backlog?
2. Define ways to implement multi-threading.
3. Define abstract class. Why is it used?

Face to face interview questions:

1. Describe singleton class. How would you implement it in multi-threaded scenario.
2. Every interviewer had somehow read the same article where it is focused on creating singleton the best way for multi-threaded environment and everyone who came in asked the same question again and again.
3. How would you load a large data using web via HTTP?

Other questions were pretty standard Java questions.
