How do you join two tables by a common value in SQL?
There were mostly questions concerning SQL and product sense: some easy technical questions like 'What commend would you use to sort results in descending order?' and 'What types of joins are there?', as well as two not difficult coding problems where I had to join tables, filter out some rows, group filtered ones and order results; when it comes to product sense, that part was quite difficult: they asked what metrics would you use to find out if two users are friends in real life and how would you find out if some user has more real-life friends than not-real-life among his friends on facebook.
How to tell whether two users are best friends on FB?
