In November 2012, I gave a seminar about technical interviews for students in CS50. I didn’t realize that the video was on youtube until today, and it has almost 5000 views! I’m glad I can keep a memento of me teaching!
A note about the video: I usually use the whiteboard when teaching and I write much neater than I do in the video. However, I had to use a tablet for video recording purposes, and it’s really hard to write on a touch screen!
