I have an interview with a top company for a data scientist position. I was made aware that they will be testing probability/statistical theory concepts.

So the question:

If you had 1 hour tops to do an all-inclusive interview about a range of topics, and wanted to test someone's knowledge of probability/statistical theory as well.... what concepts would you test?

Another way of phrasing the question:

What are the most important concepts to know from probability/statistical theory?

(I can't study everything!)

  • $\begingroup$ Questions like this are a little problematic. They don't have single, factual answers, but tend to elicit opinions. That is considered a reason for closing a question as off-topic (see our help center), note that CV is not intended as a discussion forum. I do think this is a gray area, & that there is some room for questions like this. At a minimum, you should make this Q community wiki, but be aware that it may still be closed. $\endgroup$ Jul 9, 2014 at 15:05
  • $\begingroup$ They're probably less interested in testing your knowledge of probability/statistical theory concepts (that's what academic qualifications are for) than in your ability to apply them to real-life problems. So be prepared to talk about such applications - in your previous jobs, your post-graduate theses, & in the job you hope to be doing. $\endgroup$ Jul 9, 2014 at 15:24
