I applied online. The process took 4 weeks. I interviewed at Barclays (Londres, Inglaterra) in Mar 2014
Interview
3 rounds. All on phone. I was asked general technical questions about my experience followed by questions about design patterns and object orientated programming. Threading. I was also asked about real time messaging patterns.

Interview
Terrible and very time consuming interview process. Applied online and had to complete a Business Insight Assessment. After that step, I was invited to take a HireVue online assessment, which was 5 coding questions, 12 reading articles and analyzing graph questions, 5 video response questions (one doesn't count), and 2 type a response/email to a scenario questions. You'll be drained by the end of it and it's a classic example of a company being very cheap during the interview process. At the end of it, I don't even want to work at Barclays anymore.

Interview
Applied and did two rounds online. First round very easy behavioural questions, immediately got a harder online test. Second round involved 3 quite mathsy coding questions as well as behavioural questions.
