I applied online. The process took 2 months. I interviewed at Barclays (London, England) in Dec 2016
Interview
2 online Business Insight tests, followed by a one-way video interview, then a phone interview, and then a mock business meeting and interview in the head office. The business meeting was tough, as there was a lot of information and possible questions that could have been asked. The interview was mostly behavioural and competency questions.
I applied through college or university. I interviewed at Barclays (Pune)
Interview
There was 1 online assessment, which had some MCQ questions and 2 coding problems. First coding problem was easy based on array implementation, and the second one was also easy-medium on tree implementation.
interview was very bad , the interviewer not know anything , he was googling the questions in front of me . also it was a resume screening round , he was unable to understand my resume as his domain was different , he didn't ask a single question on resume
it had online assessment, then interview round (on-campus)
online assessment had strings coding question - medium level and input output questions. medium level test over all, then interview depends highly on your luck and the interviewer
