Loopio Outbound BDR interview questions

5 interview stages. First with recruiter, then team lead, sales director, 2 team managers, another sales director. The ones with team lead and sales director were focused on prospecting skills - half Q and A, half mock call and mock email writing taking 60 mins in total. The one with two team managers were focused on culture fit taking 45 mins in total. The last one wasn't initially planned, however the company had several candidates make it to the last round so they "had" to have another round, 15 mins coffee chat, but in reality just another interview but with a shorter time length to fully address questions. Extremely unprofessional that they're calling all candidates who made it through the last round back for another interview.
