Glassdoor had a great interviewing process. It started with a 15 to 20 minute phone call to learn about the company and give you the opportunity to tell them about yourself. Very informal more of a conversation. The second round was a more formal phone call that lasted 20-30 minutes, where they went more in depth on why you thought you were good for the position along with strengths and weaknesses. Realizing the sales position was not what I was looking to pursue I chose to part ways after the second interview. Overall it was a great process and fantastic experience for an overall interview process.
