Anyway, if I were interviewing a designer, I’d look at their portfolio and just ask if they’re comfortable using whatever tool is standard at the company.
If it's a great company, has great people and creates awesome products why would a design tool of their choice be a big red flag?
At least Sketch still offers perpetual licenses and it's a proper desktop app.
Monopolies aren't good for us - so having more than one design tool provider is healthy.
It's awful collaborating and sharing files with Abstract. More and more plugins were unmaintained. And with the growth of WebGL, Figma was actually far speedier than Sketch. Sure if you're 1-2 person shop or a really big company with lots of specialized Sketch plugins, Sketch might be fine but on any other team are better off making the switch.
It's also capable of pasting vector data from Adobe Illustrator, which makes it quite useful when pipelining web assets if you're dealing with vector art done by your art/design dept. or external artists.
It's clearly become a niche product, but it's still extremely useful for what it is.
