As a counterpoint to all the negative comments here, it’s entirely possible the CTO knows it’s gonna take x time to get your company laptop, which precisely because it’s a regulated industry might mean days/weeks of you waiting around with nothing to do

In that situation it makes sense for you to bring a personal laptop which you can use to access non confidential stuff, you might not write any code in it and might just be given docs to read through

Yeah this thread is making a lot of assumptions. Maybe the machine has been ordered, or they need to do HR type onboarding for the first few hours, or any number of reasons. Every job I've ever started I bring my own machine just in case and it has been fine.

It's only a red flag when they specifically ask you to start doing work on your own machine.

I like this take. And I have been in that position before, get my self familiarized with whatever frameworks they are using.

But actual code, that's gonna need a work issued machine. They had over a week now since I accepted the offer and they have an MSP, so it's a bit odd for it to take that long.

but honestly it's still a bad look for the company that:

1. did not communicate that X timeline in advance 2. did not pre-order when they offered the offer letter or when OP signed the letter
