A lot of hoops to jump through for a glorified call centre position. One of those interviews where the interviewer is more interested in making it difficult rather than getting to know your strength. It became frustrating when the interviewer kept asking abstract questions with a specific expected answer and kept pressuring you to give him the "right" answer. I've learned that the pay is meager for an expensive city and the job is repetitive (making calls to people on job site) beforehand and was thinking of using this position only as a backup. The team has very little actual professional experience and are mostly fresh graduates with not even language skills. Maybe why they had to use case studies with fixed answers to fake expertise over interviewees. If you're not thrilled about a call centre job with little pay but high pressure, it might take up more energy than you expected and gives you unnecessary frustration caused by incompetent interviewers.
