DB has just completed his PhD at a world renowned UK university in a STEM subject. He didn't have a good time, and almost left on a number of occasions. He said the issue was poor supervision. I'm not sure if this is unusual or not, but his supervisor didn't even turn up for his viva. He also didn't like the politics, which he felt was unique to the institution.
DP has got a postdoc starting soon in an EU country. It's his last attempt at trying to make a success of academia. However he is still feeling really unhappy and I was wondering if anyone has had a similar experience and can offer some advice on how to pull through? I feel like he has been scarred by his PhD experience.
