This is an important qualifier. I'd argue that the most technical candidates are not necessarily the ones who offer the most value to companies. In fact, I would argue that "notably de-emphasizing ambition" will cancel out your technical superiority in the overwhelming majority of cases.
Here's a choice for your company's next hire:
1. A technically superior but comfortable candidate whose top priority is maintaining work-life balance and flexible work arrangements
2. A technically adequate but hungry candidate whose top priority is moving fast and learning tons
Who would you choose?
