Usually

It’s hard for me to offer guidance on questions that are usually asked at the viva.

You could search for “PhD viva questions UK” and explore the results. Adding your general research area as part of the search term might produce something more specific.

But every viva is unique and questions are always tailored by examiners to the research, the thesis and the candidate. Examiners need to explore the significant original contribution, unpick the research process and examine the capability of the candidate.

Consequently, it’s hard for someone like me without subject knowledge to suggest questions for someone – but if that candidate reflects on their research and the areas that drive examiners they will be able to identify topics to help their preparation.

There are no questions that are usually asked. There are areas that have to be explored in discussion.

Consider those areas, reflect on your research and see where that thinking leads you in your preparation.

Guarding Your Research

It’s an easy enough mistake to hear “thesis defence” and believe that you have to guard your work.

Defence brings up ideas of protection, or courtrooms, of shielding and more.

An examiner might have a pointed question or comment, but you generally don’t need to worry about them piercing the armour of words and ideas you have fashioned during your PhD.

Defending your thesis means supporting your work. Defending your thesis means providing clarity. Defending your thesis means saying more after you’ve done a lot.

You don’t need to guard your research from your examiners. You do need to be ready to show exactly what it all means at your viva.

End Well

The simplest way to end your viva well is to:

  • Check that your examiners have no more questions for you.
  • Check that you have no questions that you need to ask them.
  • Listen carefully to what your examiners are telling you through the process.

Vivas tend to conclude with short breaks for examiners to confer.

They tend to result in minor corrections for candidates.

And they tend to end after several hours of challenging discussion about interesting and potentially difficult topics of research – which is why it’s useful to breathe, take your time and make notes if you need to.

No-one wants a really long and drawn out viva process. At the same time, no-one benefits from rushing through the final stages. End your viva well.

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.

Qualified

Three qualified people is what you have, at a minimum, at your viva.

Every viva in the UK has one candidate and at least two examiners.

The latter are qualified because of how they are selected. They need to meet criteria, such as having a doctorate, experience and training. There will be a specific reason why they were asked to be your examiners rather than someone else.

You are qualified because you did the work. You invested the hours. You made something. So you’re capable now and qualified to be at your viva.

 

Remember: qualified is not a synonym for perfect. No-one at your viva is perfect or is expected to be perfect. You’re all just continuing to demonstrate your best and most capable selves.

Normal vs Typical Vivas

The normal viva doesn’t exist. It’s a myth. There’s far too much variety in research, individuals and circumstances to allow for a normal viva.

There are typical vivas. There are patterns, trends, regulations and processes that produce reliable expectations.

For example, vivas typically last several hours, conclude with a short intermission while the (typically) two examiners confer and most often result in success – with candidates being asked most often of all to complete minor corrections.

There is a tension between the seemingly opposite ideas that vivas are unique and vivas follow patterns.

Explore the patterns to prepare for your unique experience.

It’s One Day

That’s the viva: one day after many days.

A few hours after several thousand hours.

One conversation after many conversations.

One more challenge after many, many challenges.

 

Your viva is a few hours on one day. A conversation that matters. A real challenge after you have already overcome a lot of challenges. It’s not trivial but nor is it so far above and beyond anything you’ve done and everything you’re capable of.

You did the work over many thousands of hours. Show up and do a little more.

Advice > Anecdote

Your friend’s experience might be useful to know but has to be placed into the wider viva context.

One good story shouldn’t be enough to help you feel better about the viva. Similarly, one person’s negative experience shouldn’t shift you to thinking that your viva will be bad too.

Ask others for help and ask for their stories but consider them alongside the wider advice about the viva, in terms of prep, expectations and approach. One story can be interesting; the patterns and trends in many stories can be valuable.

Anecdotes about the viva are good but good advice is much, much more helpful.
