I applied online and then went in for an interview. Their office was in a good location and looked great. Two managers in the department interviewed me and they seemed nice. They asked me questions about my previous internships and research projects. They also asked me about my technical skills and if I have worked with big data sets before. The interview lasted for about an hour. It has been 1 month since my interview but they still haven't gotten back to me.

HR follow up process was the worst and slowest one I have ever experienced. Very unprofessional. They constantly change date and time right before or even after passing the interview appointment. I had to approach them and left several emails just to figure out what is going on.
