Very simple since they do a quick call to determine if you are interested in doing the technical phone screen, and then they schedule a code share technical phone screen where you speak to one of the engineers there. I list the overall experience as negative because my interviewer went to a very prestigious math/science Uni in the Boston area and interned at a FANG company. He was bored and he couldn't hide it on the technical phone screen. I've had many experiences with phone screens and they generally fall into one of a few categories: 1. helpful interviewer, reached on-site. 2. bored interviewer, still reached on-site. 3. helpful interviewer, failed to reach on-site. 4. bored interviewer, failed to reach on-site. This was in the last category. I think most interviewers, when they know they won't move you onto the next round, should focus on being friendly and helpful for the rest of the technical phone screen. The bad ones sit their like a mute fish, and that's what my interviewer was like. Meanwhile he went on and on about their culture and how friendly it is. Classic case of ingroup/outgroup mentality.
