After submitting my application a recruiter called me for a phone call screening to get to know me and my motivation to work there. It helps if you read up a bit on the company before-hand to show you're familiar with the company and what they do and for asking questions. It might also be useful on the interview with the software engineers later.

In my case, the interviewer called ,which I think made it a more authentic experience.
