Nebula (UK) Project Management - Entry Level interview questions

I applied via LinkedIn. I was emailed that I was shortlisted and invited to an interview with the manager. Everything seemed professional and in order. On the same day, i received a call saying that I am invited to the assessment centre 8:30 am until 6:00 pm. They took me and another 4 candidates to café nero, brought us drinks and asked us to write down advantages and disadvantages of door to door and business to business marketing. Then, they took us outside in the freezing cold to observe the sales promotion team - which was basically a booth in-front of tesco and two sales persons asking people for money and getting ignored for 4 hours straight. I was confused because i applied for a project management role, which had nothing to do with what I am seeing. Afterwards, they took us back to the office. That is when they started to brain wash us with the pyramid scheme and how one can become a manager in 4 weeks - and that what we saw today is just a part of the process. They never tell you it’s commission based until the end. It is a scam - because their job ads has nothing to do with the jobs they offer.
