A software engineer sat next to me and asked me a couple questions. The questions were in general easy but having someone watching over your shoulder as you code is a lot of pressure that just usually doesn't happen in the real world. The interviewer was just waiting for me to make a mistake so he can say something. We get it, you know how to solve the problem because you've done it a million times, but give people a chance to solve it on their own. I wasn't even allowed to use gdb to debug my solution, he just wanted me to one shot answer the problem on my first try which is difficult under that kind of pressure. At the end he spent about 5 minutes asking me how a void function returns a parameter and I must have said using pointers at least 3 times, but he just kept going on and on until in the end he said "the answer is pointers". I almost face palmed through my face and in to the wall behind me. I think the interviewer was pretty junior and just finished his internship judging from what he thought were tough questions and the way he spoke. Overall it was a very negative experience because even though the questions were quite easy, the interviewer made it very difficult. There is no way this kind of "watch over your shoulder" interview process leads to finding quality engineers. You either need to start here as an intern or you need to code really quickly under pressure and be very prepared for the exact question they will ask. Good luck with that Arista.
