Barclays interview questions

There were 3 interview rounds in total and one final HR round on top of these 3 rounds, Interviews were smooth and the interviewers were actively following up based on the responses. Mostly the interview revolved around the resume and some additional finance questions around the topics I've written in Resume. There were few puzzles in the third round which was with a senior trader from London office.

OA had timed sections. The sections were finance, probability and statistics, ai/ml, python and oops, DSA. This followed 3 rounds of interviews. First two were technical rounds followed by a HR round.
