A long time ago on the blog I offered some thoughts about examiners being like video game bosses:
After all of the trials and tribulations of doing research, your examiners appear through the fog, two mysterious and challenging foes! Whatever you’ve done before, the rules don’t apply to them!! They’re bigger than the other baddies, tougher, hit harder and if you’re not careful you’re doomed!!!
Which of course means you’ve made it through the game that precedes that boss battle. This stage might be trickier or tougher, but you have the skills you need because you’ve already achieved so much.
Another comparison with video game bosses to consider, for those who are familiar: the viva is the final form in the PhD boss level. No more battles after this. No sudden changes or power-ups for your examiners. Whatever they ask or do, whatever they think or say, you have maxed-out experience and skills, there’s nothing else you can learn or practise or do to get ready. You don’t need anything else.
This is the final challenge and you are ready for it.
