In my last job we used Zoom for interviews. The link we sent would work in any web browser, but if the candidate was signed into a Zoom account on their computer we'd be able to see it. I'd say >70% of them were on their company account.
Even worse when you have to do stuff like screenshare or coding. I've had candidates share their screen and have obvious proprietary material in open windows. I've seen countless email inboxes and calendars. I've seen candidates do coding exercises using internal IDEs, dev environments and dev tools. I've had them talk – fully unprompted – about internal tech and unreleased projects. And I'm talking about Google, Meta, Amazon, Coinbase, Uber.
At this point I'm convinced that a large chunk of tech interviews are happening just to extract insider info from employees.
This is more of an amusing story, but it kind of fits ...
I have a relative who started (what has become) a successful winery.
During the first few years he worked on the winery on nights/weekends, but he kept his day-job as a finance guy at a relatively large company.
He told me he had to give a presentation at the company one day, plugged his laptop into the conference room projector and up popped a spreadsheet of wine-making measurements (pH, temperature, % alcohol, etc.). He said everyone in the room laughed.
as a candidate it's pretty tough scheduling interviews past 5pm or on the weekends
Anecdotally, I've also seen the same thing, and _done_ the same thing (on the zoom accounts). A previous companies policy allowed for zoom logins on non-corp devices so that you could take a late call from home. The only thing I _ever_ use zoom for is work or interviews, so it's not like I'm going to log out after?
