Okta Sales Engineer interview questions

I applied online. I received a response a few weeks later for a quick phone conversation. That went well. I then had a talk with the hiring manager which went well and was instructed to complete a couple of questions on a "Sales Engineering Challenge" worksheet. Some of it involved coding, some of it involved using Okta's product. There really wasn't much help provided in completing the assignments and much of the work I did was looking at their documentation and figuring it out from there. Some questions were pretty straightforward from reading the documentation, others were not. When I was ready to do a presentation on the challenges that were given to me, I had a conference call. There were five different people on the call. I thought I was just going to do a presentation and answer questions about it afterward but that wasn't the case. Immediately, I started getting questions not covered on the actual challenge I was assigned and it was assumed I knew everything about their product as well as everything about SSO and OIDC. I answered most questions as best as I could but was thrown off by the whole interview format and constant interruptions. Later on, it became evident that no one on the call except the hiring manager knew that I had been assigned specific challenges to complete. All in all, it ended up being a colossal waste of time since I had to prepare so much to do the presentation. To make matters worse, they didn't even follow up with me knowing that I put a lot of work into their challenges. I put in a lot of work recording parts of my presentation for brevity, spun up an Amazon EC2 instance to complete part of the work, and completed every challenge. Okta left a very bad impression on me.
