Periscope Data Customer Solutions Engineer interview questions

HR emailed for a phone interview one week after online resume submission. HR was a little bit too aggressive but have a pretty good knowledge about the company. She is looking for someone who can jump into subject quickly and pop up questions regarding solutions immediately. I wish she had told me this when we started the interview. She started by asking if I have any questions and kept asking for more questions. Because I was quite nervous and felt surprised when she was still asking questions after 10 mins interviewing. I was forced to ask a lot of questions that I thought I would discuss with the hiring manager or other engineers. The HR did not answer those questions very well and we had some awkward discussions then moved on to my resume and experience. So be sure to prepare some appropriate questions and be confident to engage with HR to show your good communication skills.
