I applied through a recruiter. The process took 3 months. I interviewed at Barclays (New York, NY) in Sept 2012
Interview
Unduly lengthy and cumbersome - several rounds of interviews (3) over about 3 months. Initially met with a panel, then came back to meet the manager 1 on 1, then came back to meet the manager's manager 1 on 1, then came back again to meet the manager.
Technical interview with focus on SOLID principles and design patterns. Asked to write a code to sort an array using couple of algorithms and explain time and space complexity. Explain different data attributes to store data
I applied online. I interviewed at Barclays (Noida)
Interview
Interview process involves multiple rounds over 3 to 4 weeks or may take even longer. The process moves a bit slow so you need to be patient during the process but do keep following up.
Interview questions [1]
Question 1
Asked about experience in previous company, roles and responsibilities
It was 1 hour round with more focus on skills, experience; specially core java and managerial type questions. Interviewer was more interested in leetcode type problem and solution. It was like some exam, not a two way discussion.
