Interview process is more or less the same. What matters is the interviewer's behavior and attitude.

How does Barclay's being such as esteemed organization hire such guys? His attitude was that of a butcher and sounded like carpenter. With his continuous interruptions in the middle of answers, it was like he was only interviewing to showcase he is the boss in the process. My serious suggestion to Barclays HR team - Guys, keep a good interviewer, because the interviewer is representing your organization and work ethics.
