Eliq interview questions

1-First interview with HRBP 30 minutes via phone. 2-Interview with Sales Manager 3-Another interview with the Hiring Manager to discuss the assignment (a sales deck to be presented to the CEO and Co-founder) 4-Presentation plus discussion with extended team. As per the other reviews, thought it went pretty well and agreed during the call on a definitive feedback within 2/3 days but then they disappeared and never came back to me. After a few weeks of silence, finding their behavior really unprofessional, I wrote them again and in response got an automatic and cold rejection letter after 10 min - what a joke, not recommended
