Recruiter contacted few times in the last few years and I finally decided to give it chance. 1. Call with recruiter, you might be asked JS/Web questions like explain X, or what a function does. 2. Call with an engineer, it's 1 easy task that you will asked to implement step by step. 3. 2 rounds of technical interviews with more difficult questions. Last part when it went wrong for me, I had 2 rounds separated but since I live in EU, I had back to back interviews after midnight. First I was definitely sleepy even though I had some coffee/redbulls and the second one was a disaster because I couldn't sleep properly the previous night due to high caffeine. I did try to give them my preferred times which was early in the morning, but however I was given with midnight options. I don't get why they expect a person to perform well enough to pass a technical interview in the middle of the night.
