The first round was “code paring round”. As per HR, their website and email, in code pairing round we were supposed to improve a deployed infrastructure with senior thoughtworker but it was nothing like that, it was just a typical question answer round based on the terraform code, no code pairing was done. Maybe HR should inform the candidate next time that “code pairing” is just a gimmick and it will be just a normal question answer interview so he can come prepared.
