I was solicited on Linkedin by a very nice recruiter for the job. The recruiter offered to set up a phone interview. It was done within a few days. The interview lasted 30 minutes (as specified beforehand). There were two interviewers, one was a different recruiter, the other was someone in the sales engineer role. They were pleasant enough ... although of course it was a bit rushed. They started out by speaking about the company and asked a number of questions about my experience. It ended with them telling me that they would be in touch within a week if there was interest.
