Barclays Developer interview questions

There were two rounds of technical interviews, both on screen, and one round to pick the team. The first round was mainly technical questions about and algorithms. The questions were mainly focused on OOP and multithreading. The round took about 45 minutes and the most difficult question i remember was to explain the difference between a threadLocal and a shared variable in multithreading. The second round took place a week later and it involved problem solving. I had to solve one problem and explain and code the solution. I was a graph problem, similar to leetcode's "number of islands". I would say it was easy to medium in difficulty.

They sent an online assessment link. No technical questions asked only personality related questions.And we can try a mock assessment before getting into the original one.U can clearly understand the type of questions in it.
