I had a very bad experience with this company. I was interviewing with them for a dissertation supervisor role, and I got the position. I sent reference letters, and my degree certificate. Then they sent me tons of training, and asked me to grade their assignments systematically in 1 week (I applied for dissertation supervisor), and asked me to pass this as an exam. I used so many hours for 2 weeks and did not pass the exam, since I am not an expert with their grading system. I have never seen such a weird and indecent recruiting method, and I will never recommend this company to students.
