The task was to write a Python script; kind of easy if you really know the language beyond than just the syntax, know a thing about dynamic programming and some basic data formats. You would expect these with Python, so no surprise here. It took them more than two weeks(!) just to let me know whether they liked and accepted my solution and inform me about the next round. When they finally got back to me in the middle of August they only told me that we could only continue in September. They never contacted me again, so I wrote two emails to three different people (hr, project manager, team lead) and none of them bothered to even reply. Very negative experience, I don't recommend them even to my enemies. I would give them a double negative if I could.
