The hiring process included the typical online-assessment work (numerical/verbal reasoning) which as always seems somewhat straightforward. About a week after hearing I had passed this phase, I was invited to interview. The interview was split into two halves lasting about 45 minutes' each, the first was competency-focused and asked the usual "think of a time" style questions. The latter half of the interview lasted a further 45 minutes and involved reading through code and talking about what it did, what problems if any existed with it and how it could be proved. As the code chosen was from an older system, there were plenty of talking points. The interviewers were personable and friendly, clearly comfortable discussing the job and the role and encouraged answering any questions about Barclays itself - they were very much open to questions about the future work available as far as was possible to discuss. Overall, a good experience.
