Eu tive a oportunidade de trabalhar com o Cristian, para atender um dos clientes da empresa DARYUS e a sua performance foi excelente. Desde o envolvimento com o cenário, entendendo a necessidade do cliente e atendendo com qualidade e dentro do prazo desejado pelo próprio cliente. Foi uma atuação perfeita.

Desde o primeiro contato Cristian mostrou-se um aluno promissor, muito dedicado, educado e cortês no trato pessoal. Ele escuta, assimila e recebe bem as críticas e, com isso, certamente vai amadurecer fortalecido com os feedbacks de sua jornada, sem esquece-los durante sua caminhada. Possivelmente em virtude da sua jovialidade ele revela traços fortes de personalidade, mas nada como o tempo, amadurecimento e a vida para ensinar o que a academia não consegue. Consegue aprender rapidamente e com isto surpreende ao conseguir realizar tarefas complexas. Tem o ótimo vício no conhecimento e isto é fundamental para quem quer aprender, fazendo que ele seja um forte candidato ao sucesso profissional.
