Full On Net interview questions

I was contacted by phone without prior notice by someone from Full of Net. They asked generic questions like "Have you worked with X?" without really understanding what those tools were about. Then came an interview with the client, which focused entirely on outdated, academic-style questions — things like "What’s the time complexity of X algorithm," taken straight from big tech interview prep books. These kinds of questions are rarely relevant to day-to-day development and felt disconnected from real-world needs. After that, I never heard back. No feedback, no rejection, nothing. It felt like just another mass scouting operation — fishing for candidates to eventually place someone and profit from their salary. Unfortunately, this kind of exploitative model still persists in the industry.
