Add interview questions

This is a first draft of questions to ask at the interview.
They need to be made more open
Change some questions to be more open
Merge questions into one, include closures into discussion
Minor rewording
Make testing challenges questions more open
Change title of thesis to something more appealing

Less formal, hopefully formal enough. ;)
Merge questions and remove vague ones
Make experience questions more open and seperate UI from e2e
