Hackerrank interview, several programming questions, with optimizations needed, and lots of test.. plus several data oriented questions (SQL). They hire remotely "worldwide", so I have applied. After a week doing their hacker rank challenge, they came excited to me with following up, and they asked me where I am located (i'm in EU), and sadly interrupting the process by saying: You did great on the hackerrank challenge but unfortunately as I mentioned, we are unable to hire in * and so we are looking for someone who can be full time in one of our other locations such as London, Berlin, or Paris. Terrible experience and waste of my time.
