First there was a codepair round (1 hour)... a dynamic programming problem. not so hard...simple. some SQL question, data structure questions... Then they invited for F2F interview rounds... They informed me that there will be 3 F2F rounds and then 1-2 telephonic rounds with USA counterparts.. I had 2 F2F rounds of interview and then I was told that they are keeping my candidature on hold. What I have felt that their current projects are on Java, SQL, AWS tech stack.. so they are looking for experts on these technologies only. In websites, they have written that they would look out for any tech expertise...but, I think their decisions are mostly based on current project specific requirement. I had a different expectation though :)
