My one big piece of advice to anyone entering tech:
Don't get used to tech company salaries.
Don't get mortgages and car payments that you can only afford with tech company salaries.
Build as much emergency funds as you possibly can with tech company salaries.
Fully expect that you'll get laid off the exact same time the entire rest of the industry stops hiring people, and it may be a couple years before hiring starts back up again.
Sure, you may think those 6 figure salaries means you're living on easy street, but when it comes with only working 8 out of every 10 years, those numbers aren't near as good.
