A better strategy is just to not interview at uber.

I've never felt the need to bring my own laptop to a job interview. If the company asked me to bring my own, I'd consider that strange or even suspicious.

It'd be really weird for them to request you to bring a laptop, but sometimes when a company flies you out for an onsite and your return flight is that night, your options are either 1) leave your laptop with the hotel as luggage (pretty bad) or 2) bring your laptop to the interview. There's no real reason for them to know you have your laptop with you however.

they did not offer to provide me with a laptop and the interview format was such that I could google things and share some of my personal projects etc

That is weird. What kind of tech company doesn't have an old laptop or a Chromebook for such interview format? What if you don't have a personal laptop? I'm certainly not bringing my work laptop to a job interview...

The kind that's also too cheap to buy jackets for all their SREs, apparently.

This sort of penny-wise-but-pound-foolish shit is depressing, but not nearly as rare as I wish it was.
