The interview process felt unusually easy, which was a bit suspicious. The recruiter asked only a couple of questions and then asked me to complete a test assignment. I did the assignment, but received a rejection afterward. Some time later, I noticed that the bugs I had reported in my test assignment were fixed on their website. Also, the job posting has been up for several months. This makes me think they might be using test assignments as a way to get candidates to find bugs for free.
