Recruiter/HR call - Basic background check questions, your interest about position applied, Question on past work experience etc. Code Challenge - two code challenges related to monitoring of small application. Recruiter will provide details and has to complete within a week. I felt instruction for code challenge was not adequate and more open ended. There should be a phone screening on challenge you submit irrespective of you qualify or not in this round. Feedback received on challenge was not helpful and it leads to unanswered questions about where you went wrong in solving code challenge. At least evaluater should have considered approach of interviewer on this challenge. I felt even after putting so much efforts in solving challenge and presentation reviewer overlooked details submitted and evaluated on his own terms.
