Ask HN: Tips for getting into tech from Fortune 100

I'm trying to make the jump and my imposter syndrome is kicking in. I've been a manager at a Fortune 100 company for the last 5 years. First, leading a software development team. Then, leading our analytics team. I have a list of accomplishments under my belt and feel confident about my management ability.

However, having not done a job search in awhile, it seems that most managers are expected to be hands-on at a number of these tech firms. They're also looking for experience in newer tech that my current organization is just starting to investigate. I'm worried that my outdated technical background will be a liability. I'm also concerned that I don't have enough experience at the scale a tech firm operates.

So you're probably asking, why aim for a tech firm? Part of it is that it's sexy, part of it is the money, but the big driver is that at a Fortune 100 company, I'm a cost center. I want to be part of a profit driving organization where my team can have a real impact on the bottom line.

Has anyone made this jump? I'd appreciate any advice on how to approach this.
