I applied online. The process took 2 weeks. I interviewed at Barclays (London, England) in Sep 2022
Interview
I applied for their contract role through a headhunting agency. The recruiter contacted me after three days of sending my CV.
She went mute for a week then out of the blue the hiring manager sent me an interview invite with two days' notice.
I had to revise on the concepts for less than 48hrs. Some of the things I had forgotten from my post-graduate study.
There were two interviewers, one sounded like an analyst the other one was the developer.

Though the atmosphere was relaxed. It was quite extensive. These guys will make you sweat under the collar with 100 technical questions so be prepared.
The technical guy didn't seem quite impressed with me, I think he knows his Machine Learning concepts very well and he can easily catch you out.
At the time of writing this, I haven't heard from them
I was asked for a recruiter screening process which was short and consisted of basic behavioral questions, work style, visa salary, and location alignment. I never heard anything back. The recruiter was friendly and informed.
