First question was to compare two lists and print the common elements. Simple question, but I wasn't explaining my idea. They are looking for your thought process. Regardless if your answer is right or wrong. they are checking if you can think in the right manner. I didn't talk much or explain and just wrote the code. BIG MISTAKE! The second question I had to make a dictionary, which was not too hard. I got stuck a couple of places and they helped me out. But try to keep them engaged as you write code. Explain what your thinking or the ways you want to do it.
