I visited Barclays last December. The assessment centre where we had five interviews. They asked a lot questions including math, statistics, coding and behavior questions. The questions are not too hard, but the whole process is quite long compared with other companys, and it took me a whole day!
First round interview process was relatively seamless (phone call); super day was in person. 2/3 interviewers showed up one time, HR had to physically to go get one of the interviewers
I applied online. The process took 3 weeks. I interviewed at Barclays (Exeter, England) in Sep 2019
