I was asked at the end if there were any problem areas I would like to discuss that they hadnt brought up.
I said No but thanked them for offering me a rope to hang myself with.
That was taken in the good humour it was offered but I was surprised to be asked.
I think they were offering me the chance to ask experts for advice and that the viva was over and passed.

There is another possibility which should be considered.
It is possible that these people are talking about mortgages etc to make you feel bad.
They will know for certain that you have little money coming in.
Under those circumstances why would a friend continually talk about what they able to afford? This could simply be a way to boost their own ego at your expense.
I've been there and experienced this and it sounds very much like you might be facing that as well.

Friends come and go I'm afraid. It can be very hard to keep touch with people when you move away career-wise or location-wise and often you might feel that you gain little from doing so. The good news is that other people tend to come along to fill the void.

Congratulations.I am not sure I could have lasted 6 years to be honest so well done for finishing.

I am unsure why you are getting involved in her PhD at all to be honest. Why are you editing her work for example? Did she ask you to do that? Also why are you "pushing her"?
It sounds like you need to back off and leave her alone to either swim or more likely sink.
Finally, what do you mean when you say she cant work ever?

On the surface of it this looks less like support and more like domineering control but I may be misinterpreting your post.

ToL, I wouldn't overthink this TBH. I imagine you really want to get a feel for their undergraduate level of ability, ensure their motivation is right for doing that particular PhD and then, most importantly, allow your natural gut instinct to gauge the person in terms of whether you think you will get on with them, whether they fit in etc. Never ignore your gut instinct. IMO you want to find candidates who are enthusiastic, can show evidence of hard work when everyone else id at the pub and finally can demonstrate evidence of resilience when things go wrong. Evidence of independent thinking and working is also essential. Design your question to specifically tease out the characteristics you know are vital for success. Remember, you may not get many applicants so don't overthink.

This ridiculous and frankly idiotic obsession within academia that you must move around different universities is one of many many reasons why I will be bailing from academia once I finish submitting the hard bound thesis and finish this last paper.
ToL is correct to warn you about this.
I wish I had more positive news but academia is simply and depressingly full of examples of rank stupidity like this.
You will find this out when you start.

You can add the brainless obsession with chasing journal impact factors, awarding prizes for designing posters and an unhealthy obsession with university league tables to that.

Bookmark me on this. It will all drive you to drink if you let it :-D

Yeah this is not relevant.
The changes only require minor tweaks.
All that matters is whether you personally think that these are minor changes.
Dont sweat this. 2 weeks without the external needing to see the changes is minor by any reasonable definition.
Do the changes, move on and congratulations on passing.

Perhaps my internal examiner reads this forum.
Minor corrections have been approved.
Free to get hard copies printed.
It's all over.
I am way too hard and tough to cry.
So what on EARTH is this....... :-D
