Perguntas de entrevista de vagas de Sr. Software Engineer da empresa In Time Tec

They took two technical rounds and cleared all of them with ease and then they setup a exception round coz they want me to have a devop exposure as well. I mean really how it can be possible they want devops and everything after they have scheduled the first two rounds. Totally waste of time, at the end they send me a rejection email without any concrete reason
