They are straight out using people's knowledge, time and effort to work on their so-called "case studies". Senior Talent Partner reached out to me via email. We had a 30-min call mostly focused on my past experiences and behavioral questions. She then said that they will share a take-home assignment as the second step. The assignment would take 8-12 hours if you want to produce thorough work. Recruiter did not even ask about my visa situation and when I brought up the topic in the last 3 minutes, she said she will share a questionnaire with me the same day, instead, she just shared the case study and missed a promised follow-up. She also said that they have two late-stage candidates. Why are you sourcing new candidates then? I can't believe I wasted 30 minutes before a final stage interview with another company the same day. Unethical and disrespectful of people's time.
