I was asked to do a one hour assignment before even interviewing. It was set up so you can't see anything until you open the timed assignment and have one hour from that moment, so you can't do any prep work nor can you even glance at the topics before committing to it. I did it anyways and never heard a thing back, not so much as a "thank you", "received", or "we're moving forward with other candidates". Left a really sour taste in my mouth and I won't be applying again to a place that wastes their candidates' time so openly.
