CVS Health Interview Question

Not hard to prepare overall. Just need to prepare your previous experience, basic ML/stats, coding. However, their management is kind of messy. Due to their between-team movement, I joined two interview process but get the NO response from both team. (Because when I interview team A, they pull someone from Team B to fill the position instead. By the team I interview with Team B with the hc, the person moved back to Team B)
