Simplee interview questions

Phone screen, programming test, tech interview with team lead and R&D manager. It was a Codility task to implement some sort of data processing algorithm. 75 minutes for complete. Also it was additional test in SQL with following tasks: create database structure with relations; write couple of queries to this database to get necessary data. After successful passing it's 1:1 interview with team lead and after that 1:1 with R&D manager

Phone interivew and F2F with external recruiter F2F with CEO F2F with CFO, COO, CMO Another F2F with CEO Presentation to leadership team, 2 other interviews, and CEO again Too many interviews/visits to company (negative). Nice people overall and good discussions, but one in particular was rude during my presentation and the CEO not having internal issues resolved before asking for and contacting my references and discussing rough scope of an offer was a big negative. Wasted my references' time. Lesson learned: Don't provide references until you have confirmed that there are no other steps remaining until an offer is made.
