My biggest mistake was doing a MSc in AI. In hindsight it was a massive waste of time and I should have just aggressively mass applied to jobs and practiced for interviews as much as possible. After getting my BSc the rest meant nothing, portfolio / side projects, self-study, MSc, going to a high ranked university. All meant nothing, it comes down to applying / interviewing using maximum brute force. The rest in hindsight was largely irrelevant.
