This was the communication starter. (I don't understand if production support people work on web applications,java development using open sources,Microservices development with cloud and NoSQL then what the hell developers do as per him) Second arrogant question from the interviewer was why am I switching my current job so soon (which is after 2.5 years by the way) Third sarcastic comment from this person was so you have worked on three domains in the total experience of 9 years!.(Now I would like to highlight here I am a java expert and not a domain expert. Technologies are not dependent on domain. I don't understand how having worked on three domains with a rich technology skillset in 9 years of experience is bad!!!) What is your educational qualification What was your stream in engineering Have you passed SSS[And this one was the winner!!! :) ] (At first I thought I heard wrong so I just murmured yes but he asked the same question again) What is your % score for SSC What is your % score for HSC What is your % score for Engg What place have you done your SSC from Are you aware about spring AOP.I answered that I am aware but I have not worked on that. Interviewers response was "and you say you have extensive experience on spring".(I never said that neither spring AOP was on my resume.) So you have experience on spring boot, spring cloud? My answer was yes. No questions asked. Are you aware about garbage collector What is connection pool How would you implement connection pool in any of the server that you have worked on. What happens to the connection when the job is done Which one should be used standard jdbc or hibernate What are the types of jdbs statements Which one is used to execute procedures How would you check slowness of your application. For all the answers he responded with arrogance and total disrespect Tell me about your current application. What it does and all. I explained the stack and behavior. Considering his responses I assume either he had no idea what a microservice architecture is or he didn't get what I had explained because he was busy forming another sarcastic comment to pass. Extremely unprofessional and arrogant individual. Worst experience ever. Please save yourself the frustration and time. Think twice before you apply for this company. I had not read interview reviews on glassdoor before appearing for this interview. I could have saved my time,efforts and frustration of dealing with such person. The reason to give the review in such details is not due to frustration of not getting an offer but the reason is to bring this in light for candidates and HRs of this company because it is waste of time and efforts for both candidates and HRs in spite of their sincere efforts. Request to the HR: If at all you feel this review incorrect or exaggerated, please go though the VC recording for the interviews in case you maintain that. I assume since its secure medium you might have that.
