Barclays interview questions

It was a drive on Saturday. There were more than hundreds of candidates. There were 2 rounds, first round was easy and the interviewer was knowledgeable. Had discussions around my current project. Most of the questions were on how things were implemented in previous project around the architectural side. Encryption, how kafka broker authenticates a client consumer, how can you optimise kafka message delivery. How you have secured your microservices, what is HMAC. Etc Senond round was managerial, questions were scenario based. Mostly trying to trick you more like those UPSC interviews we see on youtube What will you do if you identify a bug that went in production and only you know it. Will you tell the management or quitely fix in next release What if there is a minor bug, but it only affects a few customers, will you report it to customers Have you had any disagreement with your lead or manager in previous company Both rounds were cleared and I was told I was selected l, even sumbitted the documents. But they ghosted me after that.
