AP Intego Insurance Group Front End Developer interview questions

I applied online. Then I've been contacted by Technical Recruiter he asked few basic questions and explained what are their requirements. After two days or so I've been contacted by CTO and then interview for about 30 Minutes. We discussed some basic technical discussion and about my past projects and experiences. Then I interviewed onsite at Waltham location. I had negative experience. I've been been interviewed by three employees one of them was senior a he was very polite and normal and other one was not professional at all. He was arrogant and not polite. I won't recommend interviewing here. Simply Waste of time !!
