Question related to past experience.
Asked what I did, and afterwards given a task to do with my favorite editor under 15 minutes or so. I was first told that I could use the internet to look at the official API but was then told that I cannot use solutions that are provided on the internet and instead figure it out, in the remaining 5 minutes. Totally disconnected from reality. If that is the talent that they are looking for they are delusional and will hire all cheaters that will cheat and find a way to get them the solution that they are looking for. At one point the interviewer asked if I was looking at another monitor, like he thought that I was cheating(while looking at me the whole time on the camera). I would not recommend this company to any of my friends.
