I have been interviewed at Barclays, Pune in May-2018.

Interview process is like below: Online exam (Coding + Java MCQ on Hackerearth) If you clear exam then F2F technical round (For some guys they took 2 technical rounds) If you clear technical round then values round (Which will check your behavior)

My experience: I have cleared online exam so they called me for F2F. When I reached to the venue I waited for 1 hour (I think it is okay, candidate cannot expect rounds to start instantly), after that they called me for technical discussion. Technical discussion was very good and it pure technical in Java language. Sample question are mentioned in below section.

After the technical discussion, they keep me waited for 2-2.5 hours and after that they called me for values round. My values round was not good as I am not able to answer accurately their situational questions (Like what will you do if your manager ask you to come in night shift, what will you do if your manager force you to implement wrong solution, etc)

Once values round gets over, HR keep me waited for 1 hour (That time was not tolerable) and then he told me you are selected we will call you for documents in next week.

After that 1 week passed, 2 weeks passed, 1 month passed, 2 months passed, still no response. (After a month I understand I was rejected or maybe I was on hold and some other candidate was selected)

I will be totally fine if they were told me that I was rejected/on-hold on the day of interview.

If HR does not have guts to tell the candidate about their result then there is nothing that they can do.
