The interviewer appeared a bit panicked based on the solutions I had provided specially for a question related to performance tuning in SQL Server. I have around 10 years of experience in SQL Server performance & tuning. I had given them every possible approach from start to finish on how to tune a poorly performing database step by step. Result, I got rejected. I even approached the HR for a round with some other candidate to judge my performance but the HR too highly unprofessional and said they believe in their Interviewers knowledge & judging. The interview was for team based in Hyderabad. The interview lasted for 15 mins. How can someone judge a person in 15 mins ? Save your time because politics is way to high in Hyderabad team and won't allow solid candidate to get into their hood.
