The process started with an initial call by the Lead Recruiter that led to a call with a hiring manager. After the hiring manager I was told if I could considering a senior role instead of a lead position, I would have seen this a red flag but I continued with the process anyway. I was given a coding challenge, easy, realistic work for a backend developer. That led to 4 hours of waste time. Meaning I had 5 interviews with clueless "Lead developers" testing theory instead of actual experience. Interviewers were nice but inexperience. I think the problem is how they are trying to structure their teams. I think how they consider seniority who knows more about a topic that they know and they assign them to teams, regardless of what the years of experience the person has. I was given ridiculous feedback that I was not a senior developer, when I have worked in the field for more than a decade yet their "Lead developers" and "Directors of engineering" have even less experience. Anyway the most disappointment was their intention of giving a low offer because of what the interviewers think.
