I attempted to sit the Tableau Desktop Specialist Exam yesterday, and experienced multiple problems.
I had to use my personal laptop which only has a wireless internet connection. My work laptop blocks downloads and access to the Proctor website, it is also against policy to allow external people to access and control my work laptop, so this is ruled out. The initial setup was long and messy, the setup guidance provided in advance of the test doesn't cover the installation you need to contact the Proctor, so it took a lot longer than expected. Not the end of the world as long as it didn't eat into my test time, which it didn't.
I was eventually able to install and set up the test, with the help of the Proctor. I was now connected to a VM with the test questions, data, and Tableau Desktop installed so I could start the test.
Half way through the test, Tableau Desktop on the VM froze. I was unable to do anything at all with it, be it change worksheets, move fields or even close it down! I contacted the proctor immediately, who after around 20 minutes of trying to fix it (closing via Task Manager, re-opening etc), told me it couldn't be fixed and to email email@example.com to explain what had happened. This was obviously extremely frustrating. I couldn't complete the exam or get any answers as to why it had happened, or what would happen next without contacting a third party via email, and waiting for a response.
When Loyalist responded they blamed my internet connection for Tableau freezing as I was using a wireless connection (my only option). I can't prove either way if the connection dipped at that point or not, so even if I assume it did, can that affect the Tableau software on a VM? Nothing else on the VM froze or lost connection. I was able to continue through the questions and stayed in constant contact with the Proctor.
I am just wondering if anyone else has had a similar experience, and if there is anything I can do when I re-take the test to ensure it doesn't happen again? I am the first person in my organisation to sit any of the exams, and am supposed to assess if it useful for the other 30 users to sit too. Given that they will also have to use personal laptops, likely with wireless connections, I want to ensure the process is reliable before I recommend.
