Applied online. Was asked to schedule an assesment in a 2 day period. Prepare for 1 day and gave the karat interview on the next. Karat interview was good. I cleared all testcases for 3 coding questions and answered 2/4 mcq questions in 50 mins. I was positive I did well but next day got a rejection email. Dont understand what more they expect?!! I guess a PERFECT candidate.
