MongoDB interview questions

I was contacted by a recruiter for this position. Had a handful of phone interviews, then was invited to an onsite interview. Spent 3 hrs interviewing with 2 Sales directors and the VP of Corporate sales. I thought it went well. I was invited back for their "challenge" portion of the interview. Which is a 1 hr role play of a sales meeting. This takes a good amount of time to prepare and research for. I was told if you make it this far it is a 90% done deal you will get hired. They liked my challenge and gave some feed back, then asked if I could do another role play to see how I took their feed back. This 2nd role play was canceled 5 mins after it should have started. I almost backed out at this point due to them being unprofessional and already canceling several calls last minute. The recruiter talked me into sticking it out. So I proceeded to do the 2nd role play interview with both Sales directors out of the Austin office. I was then told I did a great job and they would pass on their recommendation to hire me to the VP of Sales. At this time I was given a verbal offer, walked through what my comp plan would be, as well as stock options, as well as other things. We talked about when I would be available to start. I was then contacted and told I needed to have a call with the CRO (Chief Revenue Officer). After him canceling our meeting 3 times, I finally was able to have a brief 25 min conversation with him. Very high level about my background. Where I grew up, went to school, career path to this point, etc. 2 Days later I received a call from the sales director informing me they would not be hiring me. This comes after almost a 2 month process, a total of 4 hours of in person interviewing, Countless phone calls, many of which were canceled last minute and rescheduled. I currently have a job, and put in a ton of time and even took time off of work to pursue this, because I was told countless times how much they liked me and wanted me on the team. Only to be told I wasn't the right fit after being drug through their VERY unprofessional process. Ended up being an epic waste of time and left a very bad taste in my mouth as to the professionalism of this organization.

Standard phone interview. Recruiter will contact you to set up a time to talk over the phone. Very friendly, but asked me to clarify my graduation date four times. Got back within the week, I got rejected.
