Hope this helps someone and also they can tell why I was rejected as it was bit shocking.

I have interviwed for AWS Devops position, I have totally 10+ years of expierence but no expierence with AWS . I have worked with cloud applications and have built lot of automation tools.

My experience :
1 LP - Answered it using STAR technique. Tell me about the situtation where I knew i will miss the deadline .

I coding question - Find the Kth max and kth min element in array. Told the code how we can do it using sorting and also told if we use that it will be o(nlog) and in case of duplicates we might not get the right element as per index.

Wrote the code using heapq , I did separetly for max and min which is o(n) and space o(n)

Questions on Devops - CI, CD , Branching strategy, load balancing , DNS lookup, Softlink, Authentication etc. I answered all the questions. Interview was not ok with branching strategy.

Overall i did good job and was confident taht i will be moved to loop interview. But to my surpise i was reject. This is the interview I gave after 10 years.

Thanks for all the ones in leetcode and youtube for helping me in this prepration for the past 10 days.
