Contacted by a recruiter, interviewed in February 2015.
The whole interview process was not that difficult. They would ask pretty standard questions about previous experience, tech knowledge and a couple of competency based questions. The in-house recruiter that conducted the initial phone screening didn't really differ from the typical commission striving ones who lack to understand the concept of employer branding. Like any other place, it's pretty much a lottery of getting approached by either severe professionals or the incompetent ones, who give you reason to question the company's professionalism. The gap between these to parties was significant in my case. However, I also got to speak to some inspiring sales professionals with great people management skills.
After the brief phone screening, I was again contacted but this time by a HR-rep, who would go through my CV and ask me a few competency-based questions. Subsequently, you get invited to an onsite interview where you have to present a case on a couple of topics that are sent to you in advance. This is to test your business acumen. After that, the final round also consists of a sales simulation to test you sales skills.
The stiff hierarchy, poor progression opportunities, and task triviality (I'd talked to a familiar sales rep from SAP) made me turn down the offer.
