I asked one of my friends who worked there for 7 years in the past and he shared the resume to his ex-boss who forwarded to a HR. After the initial conversation with the HR, I was scheduled to interview with the hiring manager and this was the WORST ever interview experience in my career of 8 years. The guy started with no intro and jumped onto a question, "you know Java right ?explain me java reference types", question two "explain me blocking vs nonblocking in java". This time I interrupted and asked him - "I applied for DevOps role and why are the questions on JAVA". He said ok, "explain me how would you feed the ELB access log and parse them realtime instead of S3" to which I answered "As far as I know, Lambda can help in setting this up". Question 2 : "how would you have mapping in ECS for same port number in Docker but unique in Host for a service". Few solutions I provided and he quickly ended the call saying "Thank you. I think there some miscommunication here"
