(Continued from previous question...) Which is faster: Inserting one million rows of data, or updating one million rows of data? This could be one of the more technical questions you could ask a candidate. You are not looking for the correct answer (which is “it depends”). If they do answer correctly then examine the scenarios they lay out before you. It should be very insightful, you should get a real sense for how they think. Chances are they will guess at one or the other, which gives you the chance to talk with them. And when you do so, take the opportunity to see how the discussion goes. If they ask you lots of questions, that is a very good sign. If they just sit there, listen to your every word, accept everything you say as the truth, then consider that another red flag. No one is perfect, not even you, and you do not want to surround yourself with someone that just follows your every word. You need someone that is insightful enough to ask you more questions, you want someone that is always looking to learn. (Continued on next question...)
