I have a 4-stage interview process, the 1st stage was behavioral and aptitude test, after I had HackerRank for coding then a live interview with two senior developers (they were nice and friendly, but I had to have a great answer, add humor, and share something really touching to connect with them), after all the above I got my offer, but unfortunately lost it due to some complications which I sorted out with my recruiter, and he asked me to apply in-season, but by then Barclays no longer offered sponsorship.

There were a lot of questions about a hypothetical situation and what you would have done, and they also asked about system design basics, DSA, and your particular programming language, amongst other things.
