Started with a recruiter reaching out and a phone interview. This was followed up with a skills assessment. It was relatively simple but a couple of the questions outlined some potential dysfunction/bad processes in their product department. After finishing the evaluation I never heard back from the company. After I've spent the time to do a candidate assessment the least the company can do is respond. Based on the questions from the assessment and experience interviewing I wouldn't recommend Cornerstone.

Applied online and reached out directly via email to the recruiter. Process from initial reply to offer took around 5 weeks. Started with a phone screen, and then I had to complete a candidate exercise, which assessed problem solving, creativity, requirements gathering, and communication to different kinds of stakeholders. It wasn't too demanding or time-intensive, so that was nice. The on-site interview involved a few different formats. The first was a process-focused exercise to walk through the discovery and design process for a specific problem. Another was a lateral thinking exercise. Each interviewer asked for details about specific projects from my past. I met with a few directors and fellow PMs, and then a VP. We concluded with a self-assessment and a conversation gauging interest in the different domains / products within Cornerstone. Overall, it was a challenging process, but not overly burdensome or unreasonable.
