I applied through college or university. The process took 2 weeks. I interviewed at Barclays (New York, NY) in Jun 2011
Interview
Relatively informal, ask for you goals and discuss your strengths as well as weaknesses etc. Recently believe they've reformed the interview process. Went into the office on a hot day which is always off putting. There didn't seem to be any particular structure regarding the interview...very informal.
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.
