Expedia Group Software Developer Engineer interview questions

Expedia came to our school's career fair, the engineer asked me two basic questions about java, then arranged me for another on campus interview. The on campus interview last 30 minutes, first talk about what team am I interested in, then a technical question to write on board. Very simple programming question, given an int array, remove the duplicates. The man I met is friendly. I am waiting for the on site interview.
