Insight Global Rrecruiter interview questions

Got selected of an initial interview on campus. Lasted for about 15 minutes where 4-5 questions were asked. The question were basic questions and not relatively hard compared to other similar companies that i have interviewed for.

I was contacted by the company saying that they saw my resume online. I agreed to come in for an interview. No one knew where the guy that was supposed to interview me was. I waited for about 30 minutes when finally a man brought me in a room to interview me. He was extremely rude and overly confident. He was texting through most of the conversation. He would ask me questions, but not genuinely seem to care what the response was. Very unprofessional. After that another girl came in and I basically had the same conversation with her. They were very vague about the actual job that I would be doing. No one in the office was over 30 years old. Then, a guy came in to say hello and then said maybe we can have you in for lunch next week. It was a really strange experience. After that the recruiter contacted me a few days later wanting to know who I interviewed with. There was no further contact.
