Had and initial phone interview, was given a case study and then met with 2 people, another manager and an SVP, to present and discuss the case study. The interview experience was fine, they gave very positive feedback and told me they wanted me to come back in and meet with additional team members and would be in contact soon. I sent a thank you email directly after my interview and a follow up email a couple of weeks later. Now, almost 3 months later, no response at all. They took my proposal presented in the case study and used it online about a month later. Very disappointing and unprofessional.
