Helix Anonymous interview questions

Five interview rounds, meeting with multiple teams: Round 1- Talent Manager (phone) Round 2- Hiring Manager (phone) Round 3- Finance, Lab Round 4- Bus Ops, Finance, Legal, HR, Engineering {End} Round 5- Would have been CEO or VP-Partnerships Reached the fourth round, explanation given for not moving forward with my candidacy was not having enough 'technical' knowledge of the position. This, even after meeting with the hiring manager in an earlier round, and still having to meet with people without expertise in that knowledge area. Then why continuing to want to meet with me? This has been a huge waste of time, and it should be noted that communication with the hiring manager and talent manager was very misleading, something future interviewees should be wary about.
