They say people don't leave companies, they leave managers. And I'd have to truthfully admit that. Don't get me wrong, my manager was a wonderful person and genuinely tried his best to make my experience at Box one of the greatest (he really is a beautiful individual), but it was also his major gap as a leader. His focus was lost in a myriad of efforts to make Box great as a whole, but I think he lost sight on what it took to build the individuals that worked directly for him. From what I understand from individuals that worked for him in the past, it was for the same reason why they also moved on to other teams or companies. But this is quite common for leaders when they've only been at one company their entire career. Lack of experience generally.
