First, they approached me and asked if I was interested, to which I said yes, they gave me a test to take, which took me a few hours to answer all the questions. I sent and did a 15-minute interview with the recruiter. After that, silence, nothing more was said to me. Cut to over a month later, and they approached me yet again with the same message. When I said that I had already gone through the process and I had no feedback, they didn't say anything else. I didn't understand the purpose of it all. Detail: unpaid test.
