Gartner Director, Analyst interview questions

The interview process was ridiculous. They knew I was in final stages with another company, so they compressed my process with them. The final stage included an in-person, timed writing assignment and then a 90-minute panel review/debate. I have been writing content for my entire career, so that's never been a problem for me. However, I'm a Mac user and was forced to use a completely unfamiliar PC. I haven't touched a PC in more than a decade, so fighting with their machine wasted 1/2-1/3 of my 90-minute writing time. As a result, I caught an error in my final product with only two minutes remaining and didn't have the time to correct it. Had a I been able to use a familiar device, I know I would have had the time to apply the corrections. I then told each/every one of the three facilitators that were helping me and they said not to worry about it. However, I should have been allowed additional time to address it given what a time suck that Thinkpad was. I even told the one Gartner executive that was on-site and he told me to just admit the mistake at the start of the panel discussion, which I did. I thought the panel debate went well. I answered all questions, even those beyond the scope of the writing assignment, and thought the day went well. However, I learned the next day that the team had chosen to pass on offering me the position. So, now I'm sharing all of this to prevent future candidates from the pitfalls I had to face. This process, which they used in prior decades, seems stuck in the past despite the distinct differences of today's job market.
