[@kumarashutosh229]

One more thing for which I want to encourage you all is about language and answer delivery, why are we so obsessed with answering the queries in English, I can bet he wanted to tell more and knew more, but he was just not delivering what was in his brain just because he was not able to frame words for the answer. We can encourage interviewees to feel ok with any language. Just a thought! Thanks

[@CodeDecode]

We appreciate your opinion but you are contradicting yourself. In previous comment you said that what if the candidate is interviewed by non Indian person, here you are encouraging to answer in language other than English We are unable to understand your view point as you are contradicting urself

[@kumarashutosh229]

The good part, you gyus did a good job doing the session in front of everyone. Thanks for this. Now, some not so good part, how can you forget @transactional functionality in context of an aop. No questions on multithreading, spring-cloud-config, architecture-design. I don't think the interview problems were properly drafted and neither evenly spread across different java and spring ecosystem. Most importantly, answers were horrible without any hint of real-worked-upon examples and references, he definitely should prepare well and demonstrate his knowledge by justification. One liner never gonna help you score. Could you image if this guy was interviewed by a non-Indian person, that would be a complete mess. That's the reason they do not see us competent and non-desirable in IT sector. These are my personal opinion! I keep prepping for interview and I'm looking forward to connect with someone likeminded for a longer period consistency. Cheers and happy interviews!

[@CodeDecode]

We asked about aop and Atul never worked upon aop so how will he answer your @transactional with aop? At 00:04:15 timestamp you can see he said that “spring uses aop internally “ but he is an aware of these . Also he answered about the scenario based question that we asked that where will you keep 100s of common properties in multiple micro services. He did answer that as config server For designing we asked him to design an e-commerce application ,as fault tolerant and load balanced, he did that almost And a good interview is always driven by the answers given by candidates not by well prepared by hearted questions. Also we don’t think Indians are non competent or non desirable as we are spread across the global and at a very good positions too. Please change your mind set about Indians. We are known as hard working , smart , high IQ people. No body wants to demean us. Also we will be very happy to have you in the open ground. The community will be grateful to you if you can share your extraordinary knowledge with us. Kindly share your resume in the Google form 👍👍

@35:26 did he mention terraform on his CV ? To be honest the interview is like expecting "Dunki" 2 minute speaking. Are people not developing other than microservices?? I don't know how many in their life touched a distributed databse system eg. bank to bank, but I hear SAGA pattern in these interviews many times. Theory Theory Theory. If I am not wrong then show a full fledged distributed system that is fault tolerant?? How 2 microservices trust each other is just a matter of a few days (may be just API keys)
