Got sent a case study and was given 10 days to prepare it, 1 week after sending the case was invited to the office for a 1 hour interview with HR and a 2 hour slot with the Product Lead. Was asked for everything that was present in my LinkedIn profile by the HR and even more like what other companies have I applied to in the past, what stages of interviews I have done with them If I have, and if I was offered a position or not. Covered the case study with the product lead, who was obviously seeing it for the first time during the interview. Then was given a high school level "analytical test" requiring basic math knowledge on probability and combination.
