The Closed Door

The viva typically takes place in a small room with a small team of examiners, one person and their thesis and their history – and a closed door that screens it all off from the outside world.

There are lots of negative perceptions about what happens at vivas. The perceived attitudes of examiners, the nature of questions, the unlikely-but-possible negative outcomes – these all combine and make many candidates feel down on the whole experience.

All of this is perception though: if you ask PhD graduates typically they’ll describe a challenge but one that’s positive. Maybe tiring, but fair. Difficult but doable.

It’s hard to change the overall perception of the viva in academic culture, but you can steer yourself if it seems intimidating to you. Focus on regulations and expectations. Yes there’s a closed door and two examiners and a challenge but what can you focus on?

You’ll be asked a lot of questions but remember: you did the work.

The door is closed here and now perhaps, but you have years of work, weeks of prep and a few hours to show what you know. The closed door doesn’t mean that you’re closed off.

Small Expectations

There is research on viva lengths and the range of experiences. We could plot out the opening questions of a hundred PhD graduates to explore the first questions of vivas. We can examine the fine detail of requested corrections to see how much work is needed.

We can do this and more – and the result would be a big report that does not tell you what your viva will be like.

Keep your expectations small. Keep them simple.

  • Vivas take time. You can take your time.
  • Take the viva one question at a time.
  • Expect it to be difficult. Remember that you are good at difficult challenges.
  • Your examiners will be prepared. You can be too.
  • Most vivas result in corrections. Don’t expect perfection but don’t expect a lot.

What other small expectations do you have for your viva?

Red Carpet Treatment

There are no silly questions for a PhD candidate to ask about the viva.

I’m continually saddened though that PGR culture – and regulations and supervisors – haven’t stopped candidates believing that their examiners are some higher order of human and thus need very special treatment at the viva.

Here are three questions I’ve been asking the last six months:

  • “Do I need to arrange catering for my viva?”
  • “Is it appropriate to buy gifts for my examiners?”
  • “Is there a formal way that I’m supposed to talk to my examiners?”

Again, these aren’t silly questions: these are stressed questions by people who desperately want to do the right thing. There’s a mystery to the viva process. There’s a substantial amount of work leading to it. It’s all important so there are a lot of motivations for a lot of questions that any candidate might ask.

To the questions above: catering might be welcome, but it’s not your job to arrange it; no gifts; being polite and friendly is enough.

 

Your examiners are professionals. They’ve come to do a job. It’s an important job, no more than that.

They don’t need a red carpet rolling out.

Expect them to be prepared. They expect the same from you.

Leave the formalities there.

Knowing Your Stuff

At the viva you’re expected to know your stuff, whatever that might mean for someone in your field or discipline. Broadly speaking: you’re clever, you’ve done the work and you’re assumed to be capable.

It’s not hard to worry that you might be missing something, but keep in mind, to set the right perspective:

  • Knowing your stuff doesn’t mean you need to know everything.
  • Knowing your stuff doesn’t mean you are expected to have a fast recall of every detail.
  • Knowing your stuff doesn’t mean having read every paper.
  • Knowing your stuff doesn’t mean guessing every question your examiners might have.
  • Knowing your stuff doesn’t mean knowing all of your examiners’ stuff too.
  • Knowing your stuff doesn’t mean figuring things out quickly.

At the viva, knowing your stuff means being knowledgeable, capable and being willing to engage with your examiners’ questions and the discussion that follows from them.

To get as far as you have you must know your stuff: it’s the only way anyone could get to submission.

Arguing The Point

Defending your thesis doesn’t mean that you need to argue throughout the viva. Defending can simply be supporting what you’ve done and written, providing clarity if something isn’t as clear as you hoped or confirmation if your examiners just need a little more.

There is a possibility though that you might need to argue. You might need to say that you believe or know that you are right. You might need to say that you believe or know that your examiner’s opinion is not correct, incomplete or not seeing the whole picture.

Remember that arguing the point does not need to be assertive. You don’t need to dial your speech up to 11 to win!

Ask questions. Listen carefully. Think even more carefully. Speak clearly to get your reasons across. And be sure you know your examiner’s reasons before you argue against their point or opinion.

Thesis defence does not imply that it is under attack. It certainly doesn’t mean that you are under attack.

The Viva Roles

Examiners: two academics who accept the opportunity to examine your thesis and you. They have training, they prepare, they plan and they’re ready to do what’s required. They want to do the job well. They only take the role on if it seems interesting and right for them. They’re at your viva for a good reason, even if some of their questions might seem difficult.

 

Observers: a category that covers two particular sub-classes, the Independent Chairperson and your Supervisor.

  • The Independent Chair’s specific role is to make sure that the viva goes well. They might seem like a passive role – if they’re present at all, as not all vivas have Independent Chairs. They’ll steer the discussion if they think they need to. They’ll support newer academics taking on an Examiner role if that’s necessary.
  • If your Supervisor is observing then they are only observing; like the Chair they can’t ask or respond to questions. They sit back and watch. You get to decide if they’re present or not.

 

The Candidate: that’s you! How would you describe what you can do and what you’re there to do?

Some Examiners

Some examiners say harsh things…

Some examiners don’t prepare well…

Some examiners treat the viva as box-ticking…

Some examiners use the viva as an opportunity to be cruel…

I can’t dispute the possibility of these kinds of statements. I’ve heard them before and I’ve heard fragments of enough stories to know that these statements are true.

…for some examiners.

Not all. Not most. In fact, only for a tiny percentage.

The vast majority of academics who take on an examiner responsibility try to do it well. The vast majority prepare and plan and get ready. They’re careful and thorough. Being asked questions might not always be comfortable – but the atmosphere in the viva is not totally dictated by examiners.

Some examiners could be described as not doing the job well.

Most examiners will do what’s appropriate.

Don’t let the rare exception skew your expectations.

Learn About Examiners

An effective strategy for feeling better about the viva is to take steps to know more about the academics examining you.

  • Ask your supervisor about them. Find out why they are good choices for your viva.
  • Research their recent publications. Find out more about their specific research interests.
  • Search on YouTube to see if there are recordings of their conference talks. This can help remind you that they are real people!

It will also help to read the regulations and remind yourself what your examiners are there to do. They have training to be examiners and they want to do the job well. They’re there to examine, not tear your work apart or break you down. They’re focussed on finding the good, not amplifying the bad.

Find out a little more about them and you can encourage yourself towards a good viva.

Common Ground

A small part of viva prep is making sure that you know who your examiners are and what they do.

This does not mean that you need to become an expert in everything they do. As part of viva prep, unless you really know a lot about their work already, take time to read their most recent papers. Look for recurring ideas, themes, questions and methods. Look at their staff pages for their research interests.

Try to explore the common ground that your research shares. Look for the connections between what you do and how you do what you do. If you need to, take a little time to understand any differences between your research.

Again: a small part of viva prep is knowing who your examiners are and what they do. It helps, but make sure you spend your time well.

Overconfident For Your Viva?

It’s unlikely!

Even the most self-assured individual will probably feel some nerves and disquiet on their viva day. It’s unlikely that anything will go seriously wrong, but fairly probable that you might be asked a question you’ve never considered, face a criticism you don’t like or simply feel awkward at being in there.

So I don’t think you’ll be overconfident for your viva.

 

The one dangerous area that a PhD candidate can stray into is feeling that they need to have the last word. That they’re the only one who can be right. That they’ve considered everything.

Your viva is a discussion. Your examiners are exploring your thesis, your research and your capability. You might be the best-placed person to respond to their questions but you are not the only smart person in the room.

Listen carefully, take your time in responding and don’t forget to pause and think!
