I want to give on the job search

I feel so unlucky in the job search because I know I am a diligent and responsible person, always try to do my work good but I worked at two places and couldn’t pass the probation period. At the first place I was illegally fired, at the second place I was fired not because of my working ability and performance but because Korean colleagues didn’t like and bullied me (and they called it 의사소통문제). For the last month I was on several interviews and I have no idea what some companies are looking for because I was invited to the job interview again right after having a job interview with them. What are they thinking? I feel so lost and the whole life is like a joke. I graduated from good unis, have a good CV, who do you need?ㅠㅠ
