First round was a 1 hr knowledge based technical interview. Questions like what is the difference between a thread and a process. What's the diff between override and overload in Java.

Second round was 2 hour long technical interview. This consists of more knowledge based questions and 3 easy, commonly seen LeetCode questions.

Third round interview was on soft skills. Interview seems to go well then they ghost you for 3 months with no further reply or communications from their end.

Very unprofessional conduct from the hiring team. A complete waste of time with no feedback given. Will not recommend applying to Barclays engineering.
