I applied through University career fair and got a call after a week. The recruiter was very nice and friendly. I was asked about my background, programming skills, interests and what projects I have been working on. However, after I told him that I'm an international student, the interview seems to end there. The recruiter said that they wanted an intern with citizenship.

Definitely, Liferay doesn't know how to evaluate Front-End developers. They improvised my technical test and told I have only four hours to do it, later they sent the test to my email without asking confirmation. I did anyway but late, they told me they wanted to evaluate me in their offices. I went there and keep talking with 6 people about how React works and later they put me a new test about Liferay systems after I told them I don't know their systems. With this they gave me 2 pages of Java code without explaining what the code does...I was almost 5 hours being evaluated... Two weeks later I ask about my candidature, they answer I didn't pass because I'm not good at Java...I thought they were more serious but this process was a totally disaster and I feel they don't care at all about what a Front End does. If you're a Front End developer or want to do it, I don't recommend you to apply Liferay.
