Depends on which universe you end up in.

Is there a good AI tool that will work off a long list of bookmarks/links - you just add the link and it will handle annotating it, generating keywords, etc... and will allow you to do a full search through all the links end content to find what you were looking for?

Just using them for auto-complete alone makes me a lot more productive.

I do this all the time, partly because I use other languages. Is there actually a general preference in Python?

One of the best I have seen is to do a simple write-up of how you would solve the assigned real-world problem, discussing your approach and specific details as much as you think is necessary. Then during the interview, the problem can be discussed even further to make sure of their understanding.
